In this article, we’ll explore the top 3 questions about deep learning in more detail, providing you with valuable insights from leading experts in the field. It is hard to understand deep learning logic, but we will try to explain deep learning to a child. If you’re curious to learn more detail about deep learning and its applications, you’re in the right place. So, without further ado, let’s dive into the fascinating world of deep learning and discover why it is poised to become the driving force behind the next wave of technological innovation.

What is Deep Learning?

Deep learning is a subfield of machine learning that focuses on teaching computers to learn and recognize patterns by mimicking the way the human brain processes information. Deep learning is concerned with artificial neural networks. Artificial neural networks are algorithms that are intended to imitate the way human beings consider and understand. 

Deep learning learns automatically from examples and improves functions by examining these algorithms via vast volumes of data. At least three neural network layers are required for deep learning. For example, the deep learning behind driverless cars uses voice control in consumer devices like phones, tablets, TVs, and hands-free speakers.

How Does Deep Learning Work?

Deep learning works by training artificial neural networks to learn and make predictions or decisions. Understanding how deep learning works is crucial. The human brain comprises billions of neurons. Similarly, neural networks are also made of nodes. One neuron in the human brain gets millions of impulses from neighboring neurons. Nodes in layers are connected to nodes in neighboring layers, with each layer improving and refining the prediction or categorization. 

The amount of layers in the network influences its depth. Signs act betwixt nodes in the artificial neural network, and weights are allocated to those nodes. A heavier-weighted node will have a greater influence on the following sequence of nodes. The final layer produces an output by combining the weighted inputs.

The input and output layers of a deep neural network are the two visible layers of a deep neural network. The input layer receives data for processing, while the output layer performs the final prediction or classification. For example, if the deep learning algorithm fails to detect a pattern, it changes its weights and tries again until it has learned all the data’s patterns. 

There are two kinds of propagation while working on deep learning: forward propagation and backpropagation. Forward propagation describes how computations flow through a network. Backpropagation measures forecasting errors using techniques like gradient descent, modifies the weights and biases of the function by iterating back through the layers, and trains the model.

While working with deep learning, some well-known models, like Recurrent Neural Networks (RNN) and Convolutional Neural Networks (CNN), can be used.

Why Do We Need Deep Learning?

Deep learning is essential for image classification and natural language processing. Deep learning is required because: 

• Deep learning algorithms can independently extract features from data.
• From the given tasks, deep learning may learn complex or hidden patterns. 
• Algorithms for deep learning can process enormous amounts of data. 
• Through deep learning, complex interactions between a large number of interdependent factors can be understood.
• Deep learning may be used to examine data from a variety of sources, such as audio, video, pictures, numbers, and documents.

What’s the Difference Between Machine Learning and Deep Learning?

Machine learning and deep learning are two subsets of artificial intelligence (AI) that share similarities but also have distinct differences.

Machine learning algorithms create predictions using structured, labeled data, which is usually pre-processed to be organized in a structured manner. If you want to understand more about machine learning, check out the article What Is Machine Learning?

Deep learning is a subset of machine learning that reduces part of the data pre-processing required by machine learning. It automates feature extraction, reducing the need on human specialists. 

Here are the general and the most important differences between deep learning and machine learning:

• One of the first differences between machine learning and deep learning is that deep learning algorithms are layered in ascending order of complexity and abstraction and take significantly longer to train than machine learning algorithms. However, with more training datasets, deep learning models outperform. 
• Features and a classifier are manually chosen in machine learning to organize images. The phases of feature extraction and modeling are automated with deep learning.
• In contrast to linear machine learning algorithms, the abstraction and complexity of deep learning algorithms are stacked in a hierarchy.
• A domain expert is needed to determine the most used features in machine learning. On the other hand, deep learning gradually comprehends characteristics, negating the requirement for domain knowledge. 
• In contrast to machine learning, which relies on more basic concepts, deep learning uses artificial neural networks designed to imitate how people consider and understand.
• Machine learning does not need high-end computers and high-performance GPUs like deep learning. 
• After training with large data sets, machine learning algorithms’ performance tends to plateau, and then diminishing returns kick in. Deep learning models, on the other hand, perform better as the amount of training datasets increases.

Machine Learning, born from the visionary ideas of pioneers like Arthur Samuel in the 1950s, signifies a paradigm shift in the way computers learn and adapt. At its core, Machine Learning liberates us from the confines of explicit programming, enabling computers to glean insights from data and autonomously improve over time. As we traverse through the intricate tapestry of supervised, unsupervised, semi-supervised, and reinforcement learning, we’ll uncover the versatility of this technology and its significance across sectors like finance, healthcare, and beyond. Whether you’re a novice seeking to grasp the basics or an enthusiast aiming to explore advanced concepts, this journey into the realm of Machine Learning promises to shed light on its inner workings, applications, and the boundless opportunities it presents.

What is Machine Learning?

Machine learning is a method of teaching computers to learn from data, without being explicitly programmed. Machine learning works by training algorithms on large datasets to identify patterns and relationships within the data. These algorithms learn from examples and adjust their internal parameters to improve their performance over time. Once trained, the algorithms can make predictions or decisions based on new input data. The process involves data preprocessing to clean and prepare the data, selecting relevant features, and choosing appropriate algorithms. The trained models are then evaluated on separate test datasets to ensure their accuracy and generalization to new data. Through this iterative process of learning and testing, machine learning algorithms improve their ability to make accurate predictions or decisions in various applications.

Machine learning and deep learning are both subfields of artificial intelligence (AI) that focus on teaching computers to learn from data.  It became described in the Nineteen Fifties with the aid of AI pioneer Arthur Samuel as “the sphere of taking a look at that offers computer systems the capacity to research without explicitly being programmed.” 

Why is Machine Learning so Important?

Machine learning is critical because;

• It offers businesses a view of tendencies in consumer conduct and enterprise operations.
• Machine learning also can assist agencies in perceiving worthwhile possibilities or keeping away from unknown dangers via means of constructing specific fashions of consumer conduct.
• It’s feasible to speedy and routinely produce fashions that can examine bigger, extra complicated facts.

Is Machine Learning and Deep Learning Artificial Intelligence?

Machine learning and deep learning are both subfields of artificial intelligence (AI) that focus on teaching computers to learn from data. While AI is a broader concept that encompasses the simulation of human intelligence in machines to perform tasks, machine learning specifically focuses on the development of algorithms and models that allow computers to learn from data and improve their performance over time without being explicitly programmed. Deep Learning is a branch of machine learning that utilizes large amounts of data and intricate algorithms to train a model.

This illustration provides a clear overview of the core distinctions between artificial intelligence, machine learning, and deep learning.

Is Machine Learning Data Science?

No, the distinction among them is that data science is a subject that specializes in studying data and extracting meaning and insights from facts. Machine learning is devoted to constructing strategies that make use of facts to enhance overall performance or make predictions.

What are the Four Fundamentals of Machine Learning?

There are four primary strategies for machine learning: supervised, unsupervised, semi-supervised, and reinforcement learning. The Four Fundamentals of Machine Learning encompass distinct approaches that underpin the process of training algorithms to make informed decisions or predictions based on data.

1. Supervised Machine Learning

Supervised machine learning is a type of artificial intelligence (AI) technique that involves training a model to make predictions or decisions based on labeled data. In this approach, the algorithm learns from historical data where the input examples are paired with corresponding desired outputs. These desired outputs, also known as labels or targets, guide the learning process.

Supervised machine learning algorithms are skilled in the use of classified examples, along with an entry wherein the favored output is recognized. By studying a recognized schooling dataset, the learning set of rules produces an inferred feature to expect output values. It also can evaluate its output with the correct, meant output to discover mistakes and adjust the version accordingly.

In this video, Professor Eric Grimson from MIT introduces machine learning and shows examples of supervised learning.

The most prevalent type of machine learning employed today is supervised machine learning. It may be categorized into two vast categories:

Classification

Classification is a fundamental concept in supervised machine learning. It refers to the process of training a model to assign input data points to predefined categories or classes. In other words, the goal of classification is to develop a predictive model that can accurately classify new, unseen data points into one of the known classes based on the patterns and relationships it has learned from the training data.

Regression

Regression is another crucial concept within supervised machine learning. While classification is concerned with categorizing data points into discrete classes, regression focuses on predicting continuous numerical values based on input features. In other words, regression models are used to establish a relationship between input variables and the corresponding output variable, enabling the prediction of numeric outcomes. 

Support-vector machines (SVMs), additionally referred to as support-vector networks, are fixed of associated supervised learning techniques used for categorization and regression. 

The use of supervised learning is appropriate when you have already identified records that correspond to the output you expect to receive.

2. Unsupervised Machine Learning

Unsupervised machine learning is a branch of artificial intelligence that deals with training algorithms to uncover patterns, relationships, and structures within data without the use of labeled outputs or guidance. Unlike supervised learning, where the model learns from labeled examples, unsupervised learning focuses on finding inherent structures within the data itself. This type of learning is particularly useful for tasks where the desired outputs are not predefined or when the data lacks clear labels.

Unsupervised learning reveals hidden styles or intrinsic systems in records. The set of rules scans via records units searching out any significant connection. It can pick out segments of clients with comparable attributes who can then be dealt with in addition to advertising campaigns. Typical packages consist of net utilization mining and marketplace records evaluation.

Unsupervised machine learning is categorized into two types:

Clustering

Clustering is a fundamental technique in unsupervised machine learning that involves grouping similar data points together into clusters based on their inherent similarities. The primary goal of clustering is to identify patterns and structures within the data without any prior knowledge of the classes or categories the data should belong to. In essence, clustering aims to find natural groupings within the data that share common characteristics or traits.

Association Learning

Association Learning is a type of unsupervised machine learning that focuses on discovering interesting relationships, associations, or patterns within large datasets. This technique is particularly useful for analyzing transactional data or datasets where items are frequently purchased or used together. Association learning aims to identify co-occurrence patterns and dependencies among items in the data.

3. Semi-supervised Learning

Semi-supervised learning is a machine learning paradigm that combines elements of both supervised and unsupervised learning. In semi-supervised learning, the algorithm is trained on a dataset that contains a mixture of labeled and unlabeled examples. This approach leverages the advantages of both labeled and unlabeled data to improve the model’s performance.

Semi-supervised learning makes use of each classified and unlabeled record for schooling. This kind of learning may be used with techniques along with type regression. The first examples of this include recognizing someone’s face on a webcam. The price related to labeling is just too excessive to permit a totally classified schooling technique.

4. Reinforcement Learning

Reinforcement Learning is a machine learning paradigm that involves an agent interacting with an environment to learn how to perform actions that maximize a cumulative reward. Unlike supervised and unsupervised learning, where the model learns from labeled data or hidden patterns in data, reinforcement learning focuses on learning through trial and error based on feedback from the environment.

Reinforcement machine learning algorithms are a learning approach that interacts with its surroundings by generating movements and coming across mistakes or rewards. The maximum applicable traits of reinforcement learning are trial and error, seeking, and being behind schedule. 

The AI thing robotically takes inventory of its environment with the aid of the hit-and-trial approach, takes action, learns from experiences, and improves performance. The purpose of reinforcement learning is to research an excellent policy. 

There are several additional categories of reinforcement learning approaches or algorithms:

Positive Reinforcement Learning

Positive reinforcement learning refers to including a reinforcing stimulus after a selected behavior, e.g., including praise after a preceding behavior, to make it much more likely to appear again.

Negative Reinforcement Learning

Negative reinforcement learning refers to adding a reinforcing stimulus after a specific behavior, e.g., adding a reward after a previous behavior, to make it more likely to happen again.

What is Data Migration Software?

Software for moving data across locations is called “data migration software“. Database, application, server and data center migration can all benefit from data migration technologies. Data migration software enables easy data transfer across platforms. Simple tasks like moving files from one hard drive to another can be included, as well as more complex tasks like migrating an entire database from one server to a cloud or another on-premises server. The integrity of your data depends critically on the software you use for data transfer. The right data transfer software can assist you in achieving business objectives, from reducing disruptions to increasing on-time delivery rates.

How Do You Use Data Migration Software?

One of two data migration tools is available for usage in your company. Pre-implementation and post-implementation are a few of these. Your data migration to a new system starts with pre-implementation software. It will take a substantial amount of time and money to move all of your current data from the old systems to the new ones. After the migration is finished, post-implementation software is utilized to enable you to modify the new system in tiny doses as necessary without doing another extensive migration.

What Features Do You Need in Data Migration Software?

It could be challenging to select the finest data migration software. Various elements must be considered, including pricing, budget, migration procedure, etc. While there are brand-specific data conversion tools (for example, Samsung data migration software and Intel data migration software), data migration solutions generally have the same standard functionality. Here are some typical characteristics to think about:

Usefulness

Select a migrating data tool with plenty of features at all times. Many unexpected difficulties may develop throughout the procedure, so it is prudent to select software that can provide something additional. Watch out for the following characteristics:

• Planning and scheduling
• Before transfer, data profiling and analysis are performed
• Loading, Extraction, and Transformation (ETL)
• Designing migrations
• Testing
• Quality control and validation

Flexibility

The cost of data migration software might be pretty high. In order to satisfy the expectations of a growing company, it is wise to use a scalable data transmission technology.

Data Security

Cyberattacks are always aimed at digital data. Choose products that provide top-tier anti-malware features, such as web filtering, on-demand antivirus scans, and AI-enhanced behavioral detection.

Usability

Data migration technologies should be simple to use for your IT team. Adoption at the corporate level leads to tremendous success. Make sure your data migration software makes the data translation procedure simple.

Customer Support

Perhaps the most crucial quality to consider is customer service. Employees of the company may not always be knowledgeable about software difficulties. These difficulties may create a delay in job completion and project completion. Unexpected hurdles might appear at any time. That is why it is critical to select a data migration platform that provides timely and customer-focused assistance. Additionally, remember elements such as data sources and destinations, speed, debugging, etc.

Conclusion

Data may be transferred between computers, and disk clones can be created using these tools. Your needs, resources, size, and migration objectives should all be taken into account when selecting the best data transfer technology. For many reasons, including updating the company’s digital infrastructure or security concerns, data migration may be necessary.

You might want to use DAEMON Tools Pro 8 if security concerns you. You should use MiniTool Partition Wizard if you own a small business or require a tool for personal use. Acronis True Image offers all the tools you might require for data migration, so overall, I’d recommend it. Data migration between HDDs, SSDs, or HDDs and SSDs is made more accessible by this. You can transfer data from iOS and Android using the data migration software, and vice versa.

As the Internet era develops, we generate enormous data each moment. As a result, the amount of data floating around the internet is expected to reach 163 zettabytes by 2025. Patterns and correlations revealed by powerful analytics in massive data sets are informing planning and decision-making. 

The Internet of Things (IoT) is a network of real-world objects with electronics, software, sensors, actuators, and network connections like furniture, cars, household appliances, and other things. Are you able to imagine these devices producing data? These examples are truly amazing and exciting. 

As we all know, big data has arrived, and therefore the explosion of creativity that it brings can’t be overstated. Within the twenty-first century, everyone and everything is affected. As individuals, we contribute to big data by generating data from our computers, mobile devices, audio/video, networks, log files, transactional applications, web, and social media, yet as machine sensors of varied types embedded during a style of environments like hospitals, metro stations, markets, and virtually every device that generates data on a routine. 

At least 53% of companies utilize big data to gain knowledge, save money, and boost profits. One of the most significant tech improvements of the digital era is big data. It affects almost every facet of our existence, including regular buying decisions and shopping behaviors. Today’s big data may become small data tomorrow. Let’s explain the definition of big data.

What is Big Data?

The term “big data” refers to big data analytics, data visualization, and the uses of big data techniques. It can be described as amounts of datasets that surpass a petabyte, i.e., equal to one million gigabytes or 10¹⁵ byte size. It is used centralized database architecture in traditional databases, and it is used distributed architecture. 

So, what is the definition of big data? There are lots of definitions to explain the term “big data.” Big data definitions are generally used about “characteristics of datasets”, “structure of datasets”, “amount of datasets”, “using aims of datasets”, and “capacity of database”. 

It can be described as characteristics of datasets that are immense in Volume (size/the amount of data managed), Velocity (rate of change/speed/ the rate of incoming data), and Variety (the caliber and correctness of the incoming data), which was also introduced by Doug Laney, a Gartner analyst, was one of the original data types that Laney initially recognized in research released in 2001, also added Veracity (the reliability and correctness of the data being received), Value and Variability. 

Big data can be described as amounts of datasets that surpass a petabyte, i.e., equal to one million gigabytes or 10¹⁵ byte size, i.e., huge, complex, and high-velocity dataset. Recognized as more than one gigabit (1 GB) in size throughout the late 1990s and early 2000s. 

According to some authorities, big data can be defined as three structures of datasets with an ample volume of structured, semi-structured, and unstructured data or as two structures of datasets as structured and unstructured.

Big data can be identified using the aims of datasets that are used in analyzing the past dataset to do future forecasting and reveal patterns, trends, and associations. 

Big data is defined as the capability of a repository or big data management datasets whose volume or form surpasses that of conventional relational database systems to acquire, administer, store, and analyze the data quickly. 

Characteristics or Vs. of big data 

Is there any interesting thing in the heading according to you? Yeah! It’s written as “Vs. of big data”. All right, any idea what the V means? Let’s explain! 

There are mainly three words that start with “V” to explain big data characteristics. These words are “volume”, “variety” and “velocity”. More recently, some other words starting with “V” have been included in the definition of big data. These words are “veracity”, “value” and “variability”. There are six words starting with “V” that explain the characteristics of big data totally. Let’s explain the meaning of the V’s;

• Volume means “the sum of data acquired from different sources”.
• Variety is simply another word for “types of data“. Data can be completely unstructured, partially structured, or structured.
• Velocity means the generated big data’s speed. 
• Veracity means the degree to which big data can be trusted. 
• Value means the business value of the data collected. 
• Variability means a way of defining unpredictable data flow.

History of the Big Data

Background on Big Data In the 1950s, businesses used basic analytics on data in a spreadsheet that was manually analyzed to find trends and insights. People became aware of just how much data was produced by users via YouTube, Facebook, etc., around 2005. Hadoop was developed that same year, and Spark was developed in 2014 for analyzing big data.

Table-1: Big Data Phases

The origins of data analysis, which led to the development of modern big data analytics, may be traced back to London in the 17th century.

2001– Doug Laney introduced Volume, Variety, and Velocity (the 3Vs) in 2001 to describe the characteristics of big data. In the same year, the phrase “software-as-a-service” (SaaS) was first used.

2005– Doug Cutting and Mike Cafarella of Yahoo developed Apache High Availability Distributed Object-Oriented Platform (Hadoop), an open-source framework for storing and processing large data sets. Since then, big data analytics tools have undergone continuous improvement. 

2006– 2006 is the year that Amazon Web Services (AWS) launches its cloud computing services. 

2007– The phrase “big data” was originally used in 2007 by Wired in his article “The End of Theory: The Data Deluge Makes the Scientific Method Obsolete.”

2008– A team of computer science academics highlighted how big data is profoundly altering how businesses and organizations conduct business in their study, “Big Data Computing: Creating Revolutionary Breakthroughs in Commerce, Science, and Society.”

2010– People now produce as much information each day as they did from the beginning of civilization until 2003, according to Google CEO Eric Schmidt.

2014– The Internet of Things (IoT) became popular, with an estimated 3.7 billion connected devices every day. In the United States, mobile devices now outnumber desktop computers for the first time. Apache Spark was introduced. 

2017– Only in the past two years has 90% of the world’s data been produced, and according to IBM, 2.5 quintillion bytes (18 zeros) of data is being produced daily.

2020– The market for big data and business analytics was estimated to be worth $193 billion in 2019 and is projected to increase to $420.98 billion by 2027 at an annual compound rate of growth of 10.9 percent, according to Allied Market Research. 

2021– By 2025, we’re projected to have produced roughly 181 zettabytes of data (1 zettabyte = 1 trillion gigabytes), having already produced more than 79 zettabytes by 2021.

Who Uses Big Data?

Many major businesses embrace big data analytics to get relevant insights and make better-informed decisions regarding product strategy, sales, marketing, consumer service, and operations. Big Data technologies are extremely beneficial to businesses in terms of increasing efficiency and developing new data-driven services. 

Big data is now an essential component of analysis and is needed to comprehend corporate growth and create additional growth-promoting tactics. There are numerous applications for big data;

Retail: 

Retailers are increasingly using Big Data to identify customer behavior trends, evaluate a range of factors to determine optimal costing, and evaluate user engagement to provide a more individualized experience in the form of suggestions, targeted advertising, up-selling, and rewards programs, as well as to manage supply chain fluctuations as early as possible. 

In order to forecast consumer behavior, online merchants and retailers utilize data from search histories, reviews online, shopping histories, and other resources.

Manufacturing: 

To manage their supply networks, manufacturing organizations employ big data. Stock, purchasing, shipping, and returns are defined and forecasted using predictive analytics.

Banking: 

Entire financial ecosystem is changing dramatically. Big data systems are used by financial services firms for risk management, real-time market data analysis, putting an end to fraud in its tracks, maximizing return on investment, obtaining operational excellence, and reducing hidden operational costs, thereby saving money and increasing productivity. 

Health Care: 

Modern healthcare management places emphasis on data analytics to improve patient treatment, lower healthcare delivery costs, and improve patient care operations. Big Data‘s contribution to the healthcare domain has grown significantly. It is gradually but steadily having a significant impact on the vast healthcare industry. It is now being used by providers and practice organizations for a variety of purposes;

• Provides up-to-date information on infectious disease threats or outbreaks to healthcare organizations and government agencies, 
• Early symptom detection to avoid preventable diseases,
• Epidemic outbreak prediction and foreseeing problems such as emerging pandemics and drug interactions.

Why are Big Data and Big Data Analytics Important?

By looking at client profiles, a business may concentrate on what its consumers want, what demographics its paying customers belong to, and what demographic they fall into. They aid in the identification of patterns, the calculation of risk portfolios, and the detection of fraudulent behavior before serious damage is done. 

Businesses can use outside intelligence to fine-tune their business strategies when making decisions. New systems created using Big Data technologies are replacing outdated systems for collecting customer feedback.

How does Big Data work?

Big data generates fresh insights, which in turn generates new possibilities and business models. The primary three steps are integrating, managing, and analyzing big data. 

Integrate: 

Big data combine information from numerous sources and applications. Inadequate traditional data integration techniques include extract, transform, and load (ETL). New methods and technologies are needed to analyze terabyte- or petabyte-sized large data sets. You should bring in the info, process it, and assure that it is prepared and available for usage by your analysts throughout the integration.

Manage: 

Your options include a hybrid storage system, on-premises storage, or the cloud. You may use whatever processing needs and process engines you choose, and you can preserve your data in every form you desire. Many people select their storage solution based on where their data are currently stored. The cloud is steadily gaining popularity as it supports your current compute needs and lets you spin up resources as needed.

Analyze: 

Your big data investment yields results when you examine and use your data. You’ll gain fresh perspectives by performing a visual analysis of your various data sets. I delve deeper into the data to uncover new information. Educate others about your discoveries. To construct data models, they employ machine learning and artificial intelligence.

How Does Big Data Analytics Work?

By gaining valuable insights from patient data, big data analytics can assist healthcare professionals in finding novel diagnoses and treatment options. 

Big Data analytics analyze current data and predict the longer term using data processing, AI, and machine learning. The benefits of massive data analytics include making informed decisions for organizations, better risk management, and improved customer experience. 

Now let’s discuss how big data analytics functions work: 

Stage 1: Analysis of the Business Case

A business case establishes the aim and purpose of the analysis and is the first step in the big data analytics lifecycle.

Stage 2: Identifying Data Sources

Numerous data sources are discovered in this phase.

Stage 3: Data Filtering

At this stage, corrupt data is removed from all of the previously identified data.

Stage 4: Extracting of Data

Stage 4 involves extracting and then transforming data that is unsuitable for the application.

Stage 5: Data Aggregation

Data from various datasets that share the same fields is combined in stage five, data aggregation.

Stage 6: Analysis of Data

To uncover pertinent information, data is evaluated utilizing analytical and statistical methods.

Stage 7: Data visualization

Big data analysts can produce visual representations of their analysis using programs like Tableau, Power BI, and QlikView.

Stage 8: Final Analysis’s Outcome

The final analysis results are made accessible to business stakeholders at stage 8 of the Big Data analytics lifecycle so they can take the necessary action.

Challenges of Big Data

Despite the development of new data storage technologies, data volumes are doubling every two years. Curating and preparing data for use takes up 50% to 80% of the time that data scientists spend on it. It takes a lot of work to create clean data or data that is pertinent to the client and set up to allow for in-depth analysis. Organizations still struggle to manage their data and come up with efficient storage solutions. Five areas, in particular, are crucial in this process. These are; 

Big Data Governance: 

The challenges of data governance are complex, necessitating a combination of policies and technology. Organizations often create an internal team to create governance policies and processes. Additionally, they make investments in high-end data management solutions for data integration, quality control, and integrity management.

Leadership: 

In the big data era, businesses succeed because they have more or better data and because their leadership teams have established clear objectives and success criteria. Big data‘s power does not replace the need for judgment or human insight. Companies that can do all this while changing how their organizations make decisions will be successful in the coming decade. 

Big Data Security:

It’s crucial now more than ever to safeguard your data in light of the increase in data breaches. Your analytics system may experience security problems as it develops. Some of these worries can be reduced by encrypting your data, following security audits, and being cautious.

Big Data management:

Data volumes are still increasing, and a large portion of it is in unstructured data types, including speech, videos, social platforms, photographs, and inputs from mobile devices. These can be difficult to find and analyze, necessitating the use of sophisticated technologies such as AI and machine learning. MongoDB is a well-known big data solution because it can handle a variety of data formats.

Finding and Retaining the Simplest Big Data Talent:

As data become more affordable, data supplements become more valuable. Although statistics are important, many of the crucial methods for handling large amounts of data are rarely covered in statistics courses. Expertise in experimental design can assist in bridging the correlation-cause gap. The best data scientists are also fluent in business terminology.

Best Practices of Big Data in Today’s World

Amazon Prime makes programming recommendations based on Big Data analytics for individual users. Google famously demonstrated that it could forecast flu outbreaks based on when and where people searched for flu-related terms. Walmart uses real-time data from its point-of-sale system to manage pricing, inventory, and supply chain. PayPal decides what precautions it must take to protect its customers from fraudulent transactions.

Conclusion

As mentioned above, big data is in our daily life. As people and devices via IoT are also a part of big data. Because we create lots of raw data every day via watching/writing from Youtube, Facebook, Instagram, Netflix, etc. Learning data science will be very important for you if you own a business or planning to have a good career path. To learn the basics of data analytics, you may consider taking the Clarusway data analytics course from one of the best data science Bootcamps. 

A bad strategy means losing money for a company. Therefore, you should check whether our analysis results are accurate or not. In this article, you will learn to match your analysis results using Python, SQL, and Tableau and try to get the same results.

There is a selling bicycle data in the SQL database in which there are nine brands, seven categories, and 321 products of bicycles. Time starts from 2018-01-01 to 2020-12-28. There are three stores total of 10 persons. We connect to the database, pull data, and analyze it using Python and Tableau. We also analyze data from the database using Microsoft SQL Server Management Studio. 

1. Creating SQL Schema

First, we prepare the database schema beforehand, as shown in Table 1 below. The table shows the connection between the nine tables. It is based on a relational database management system (RDBMS).

There are nine tables. These table names are; product.brand, product.category, product.stock, sale.customer, sale.order_item, sale.orders, sale.staff, sale.store

Table-1: Database Schema in Microsoft SQL Server Management Studio

2. Connection with Python

Now we connect to the database using python scripts. It is shown the steps of this phase below.

Step 1: Create a Python File as Jupyter Notebook

In this step, we create a new python file as Jupyter Notebook named “ConnectionToSQLServerWithPython.ipynb” which we save into 

C:\Users\TOSHIBA\Desktop\CLARUSWAY\ML\MyProjects\SampleSales.

 You may save your file wherever you want on your local drive. 

Step 2: Import Pyodbc/Pandas in Our Python File

The next step is to import pyodbc and pandas modules in our Python file. It is one of the most favored languages all over the world. Open Database Connectivity (ODBC) is a database driver, and Pyodbc brings Python and ODBC together. Pandas is a powerful manipulation tool built on top of the Python programming language. You may learn more details about python from the https://pandas.pydata.org/. 

Step 3: Regulate the Connection String

Now, we regulate our connection string. For this example, my driver should be the SQL Server version we use; here is SQL Server 2017. There are also SQL Server 2016/2014/2012 versions. Now, we connect to SQL Server as “localhost“ using Windows Authentication. Our main database which we connect to is “SampleSales“. Hence, we regulate our connection via ODBC Driver shown below:

Step 4: Execute SQL Query by Creating Cursor from Connection

In this step, we execute the SQL query by creating a cursor, as in the example below. We give just an example of a query below. It may change according to our analysis. We can see the code looks like this:

Step 5: Recall Inquiry Result from Cursor

In this phase, we use the cursor.fetchall() method to get the query results by using for loop from the cursor:

Step 6: Close Cursor/Connection

In this last phase, we close both cursor and connection to avoid leaving an open database. To do this, we write the below commands:

Step 7: Full Code of The Example

Below, we can find this example’s full code.

3. Connection to Database from Tableau

First, after opening Tableau, we should connect to Microsoft SQL Server. We should click the “More” button and select Microsoft SQL Server.

Table-2:  Connecting to Microsoft SQL Server

After that, we see the page below. We should fill in the blanks about this page’s server name, database name, and authentication area. For the server name, we should write our computer’s name. We should note the database name we want to connect in the Microsoft SQL Server Management Studio for the database name. Here, we use the “SampleSales” database.

In the authentication area, there are two choices; one of them is “Use Windows Authentication (preferred),” and the other one is “Use a specific username and password.” Choose which one is appropriate for you. If you choose “Use Windows Authentication (preferred),” you can connect automatically. If you choose “Use a specific username and password” we should write our username and password to the area. Lastly, we should click the “Sign in” button.

Table-3: Connecting to Microsoft SQL Server Management Studio.

After that, we see a table shown below. There are the “SampleSales” database’s tables in the table.

Table-4: Tableau’s Data Source Page

These tables are the same as the Microsoft SQL Server Management Studio’s “SampleSales” database tables below.

Table-5: “SampleSales” database tables in Microsoft SQL Server Management Studio

After that, we join the tables with each other. We use the “relationships” method for this aim. It is important to join the tables like the database schema shown in Table 1.

Table-6: Joining The Tables With Each Other

4. Analyze Two Examples

Now, it is time to analyze. We want to show two examples. One is to analyze the “average product prices of the brands.” The other is “find average product price is more than 1000.”

Example 1: Analyze the average product prices of the brands

It may change the product prices year by year for a company due to many factors. As a company, we wonder how much they mean product prices for three years. We show the analysis results using Python, SQL, and Tableau, respectively.

Step-1: Show With Python

Now, we analyze the question with python. We write the query for the question to which we want to find the answer. Then, we find the answer via for loop. We see the products’ average prices. For example, the product named Trek’s mean product price is 2500. These results are shown in descending form.

Table-7: Analyze Results with Python

Step-2: Show with SQL

Now, we analyze the question with SQL. We write the query for the question to which we want to find the answer. Then, we find the answer under the query. We see the products’ average prices. For example, the product named Trek’s mean product price is 2500. As we see, its product price is the same as the result we get from the python result. These results are shown in descending form.

Table-8: Analyze Result With SQL

Step-3: Show With Tableau

Now, we analyze the question with Tableau. We use the product.brand and order_item tables. We use brand_id and brand_name columns from product.brand table and use the list_price column from the order_item table as seen in Table 9. We see the products’ average prices below. For example, the product named Trek’s mean product price is 2500. As we see, its product price is the same as the result we get from python and SQL results. These results are shown in descending form as python and SQL results.

Table-9: Analyze Result With Tableau

Example 2: Find Average Product Price Is More Than 1000

We suppose that we want to learn which brands are expensive for us. So, we find which products’ average price is more than 1000. We show the results of analyzing Python, SQL, and Tableau. 

Step-1: Show With Python 

Now, we analyze the question with python. We write the query for the question to which we want to find the answer. Then, we find the answer via for loop. We see the products average prices more than 1000. As a result, we see that there are three brands. For example, the product named Surly’s mean product price is 1331.

Table-10: Analyze Results with Python

 Step-2: Show with SQL

Now, we analyze the question with SQL. We write the query for the question to which we want to find the answer. Then, we find the answer under the query. We see the products’ average prices are more than 1000. As a result, there are three brands with an average price of more than 1000. Their names are the same as the result we find via python.

Table-11: Analyze Result With SQL

Step-3: Show With Tableau 

Now, we analyze the question with Tableau. We use product.brand and order_item tables again. We use brand_id and brand_name columns from product.brand table and use the list_price column from the order_item table as seen in Table 12. We see the products’ average prices more than 1000 below. For example, the product named Surly’s mean product price is 1332 rounded. As we see, there are three brands same as the result we get from python and SQL results. These results are shown in descending form as python and SQL results.

Table-12: Analyze Result With Tableau

5. Conclusion 

It is very important for data analyst dummies whether they analyze data true or not. In this article, we analyzed the data using Python, SQL, and Tableau simultaneously and got the same results. Hence, we are sure that our analysis is true. You can analyze every dataset using this method told elbow and ensure your analysis results.

According to Harvard Business Review, data scientist is “The Sexiest Job of the 21st Century” in October-2012. Of course, we can’t cover every potential data science job title that a company might use in this article. Still, we can talk about some of the significant roles like data analyst, data scientist, and data engineering in the data science universe, how they differ, and the progression in the field if you’re starting in that role.

1- Data Analyst

Data analyst jobs is typically considered entry-level data scientist job in the DS area. However, it is important to note that not all data analysts are junior; therefore, data analyst salaries vary widely.

As a data analyst, your primary job is to analyze a company or industry data and use it to answer business questions, interpreting those answers and communicating them to other teams in your company. For example, To assess the effectiveness of a recent marketing campaign and find strengths and weaknesses, as a data analyst, you might be asked to examine sales data from the campaign.

2- Data Scientist

Data scientist is another data science job that you can apply. Data scientists do the same things as data analysts, but they also use data to build models to predict target features. A data scientist is also supposed to search for new patterns, unseen trends such as management could not capture. This point brings data scientists more responsibility and more freedom.

A data scientist might be asked to evaluate how a change in marketing strategy could affect your company’s bottom line. First, of course, data analysis would be necessary (acquiring, cleaning, and visualizing data). Still, it would also probably require building and training a machine learning algorithm that can predict the future based on historical data.

Data scientists are responsible for exploring information from large amounts of organized and not organized data to develop a solution for business needs and targets. Accordingly, the data scientist’s duty is becoming increasingly important as businesses rely more heavily on data analytics to make a decision and lean on automation and machine learning as the main components of their IT strategies.

A data scientist’s main objective is to organize and analyze large amounts of data, often using software specifically designed for the task. The final results of a data scientist’s analysis need to be easy enough for all shareholders and non-IT folk to understand.

A data scientist’s approach to data analysis varies depending on their business sector and the specific needs of the business or department they are working for. The business leader and department manager must clarify what they are looking for before a data scientist can find meaning inside the data. In order to achieve company or departmental goals, data scientists need enough domain expertise to turn data into information-based deliverables such as prediction engines, pattern detection analysis, optimization algorithms, and so on.

General Duties of Data Scientists

• The gathering of large data sets and converting them into more helpful formats,
• Wrestling with different types of data, sources of data by using varied programming tools such as python, R, etc.,
• Mining the nuggets of information which is under the surface of big data, reveal the unseen trends, patterns and transform them to actionable information for company/organizations
• Using machine learning and deep learning techniques
• Contact and communicate with different shareholders regularly: IT departments, decision-makers, data source, and related executives.

3- Data Engineering

Data engineering is another data science job that you can apply for. A data engineer’s job is to identify patterns in data sets and develop algorithms to make raw data more useful for the enterprise. Several technical skills are needed for this IT role, including understanding SQL databases and comprehensive programming skills. As well as technical skills, data engineers must also be able to communicate across departments to understand what business leaders are trying to accomplish with the company’s large datasets.

Data engineers are often responsible for building algorithms to help give easier access to raw data, but to do this, they need to understand the company’s or client’s objectives. It’s important to have business goals in line when working with data, especially for companies that handle large and complex datasets and databases.

Data engineers also need to understand how to optimize data retrieval and develop dashboards, reports, and other visualizations for stakeholders. Depending on the organization, data engineers may also be responsible for communicating data trends. Larger organizations often have multiple data analysts or scientists to help understand data, while smaller companies might rely on a data engineer to work in both roles.

Although data engineers traditionally come from IT-based roles/education, IT bootcamps make it possible to change career paths for non-IT / non-technical professionals. It also helps build a convincing resume to land in data engineering or data science roles. Data engineers need high-level technical skills such as SQL, database design, python, Java.

4- Data Science Internship

Today, as mentioned above, data scientists and/or data analysts/data engineers are those who’ve changed their career path by attending a Bootcamp or certification program. So to eliminate their disadvantages against IT-origin professionals who have experience in the IT industry, it is very recommended to apply for data science Internship programs. By doing so, they will gain industry experience, enrich their resumes.

Do not forget to Study Data Science Interview Questions

Once you are ready to apply for a data science-related job, it is time to look at data science interviews questions. Data science interview questions can be the most challenging part of any job interview. During a data science interview, an interviewer will typically ask questions ranging from broad industry-related questions to more specific, industry-specific questions.

In addition, depending on the company’s data science department, questions might be given to deal with theoretical concepts. The questions chosen are to assess whether the candidate is well-versed in the theoretical concepts of data science and how they interact with real-life examples. Candidates that successfully pass the first round of interviews are often given the lead role in the data-science department.

Before the interviewee even gets to begin the data-science interview process, it’s important to get a few things in order. For starters, it’s crucial to find a data-science company with which candidates have a good rapport. This means it’s important to be aware of the typical responsibilities and job descriptions of the company and have an idea about the types of questions they will likely be asked. If candidates don’t feel at ease in the office environment of a data-science company, or if they are unsure how to perform in an interview based on their resume, their chances of getting hired in that company are slim to none.

Data scientists must be able to demonstrate that they can not only master the theory behind the data of science but can execute it in real-life examples. In addition, data scientists must show that they can solve problems presented to them. Candidates that come unprepared will be unsuccessful throughout the entire interview process. Therefore, data scientists must practice interview questions until they’re confident that they’ve adequately grasped all the essential information necessary for the position.

Data Science vs Data Analytics

It might be a good idea to take a quick look at Data Analytics while talking about data science and data science jobs. Data science deals mainly with studying large sets of unprocessed data; this is why it is so commonly used in scientific research, such as statistics, machine learning, and the internet. On the other hand, data analysis is an application that uses tools to analyze large sets of unprocessed data and draw conclusions based on the information they contain. So while there may be some similarities between data science and analytics, they are two completely different concepts, and there is no reason to think they should be the same.

Data science deals mainly with the use of mathematical techniques to solve problems and come up with solutions. On the other hand, data analytics is more concerned with how the business or company uses the data. Data science is heavily used in the field of computers. It deals largely with mathematical techniques and algorithmically taking pieces of code and translating them into actual solutions. While there may be some similarities between Data Science and Analytics, they are two entirely different concepts, and there is no reason to think they should be the same.

There are plenty of books and websites out there about the strengths and weaknesses of Data Science vs Data Analytics. However, if you have business problems that need to be solved using big data techniques, it would be wise to take a Data Science certification course before starting your research. Not only will it show you the basics of this technology, it will also put you on the right track to success. Data Science certification courses are widely available online; simply type in “data science certification” into any search engine, and you’ll find plenty of options to choose from.

It’s worth mentioning here that data analyst jobs are generally considered as entry-level positions in the field of Data Science.

Begin A Rewarding Career with IT Bootcamps

IT bootcamps are one of the fastest-growing fields in information technology, with more companies joining every year. Similarly, data science bootcamps have become increasingly popular among IT professionals because of their low cost and emphasis on applied data science and analytics.

IT professionals looking to get into IT boot camps can be sure that data science and analytics can be taught efficiently at IT bootcamps. But they will also need to take business development and leadership courses to prepare themselves for data science and data analytics jobs. Bootcamps for data science training typically teach the basic principles and technology behind Hadoop, Map-Reduce, and the new streaming frameworks like Spark.

Data analytics and business intelligence can be defined as the process of discovering business patterns from massive amounts of data. Common examples of this data include customer data, sales figures, social networks, and healthcare data, to name a few. These large volumes of data can allow an analyst to discover relationships and trends that would otherwise have been difficult to uncover without more in-depth research. Many large-scale companies employ data scientists and analysts to provide IT companies with this advanced capability, allowing them to leverage existing data and rapidly analyze it to discover business problems and opportunities.

IT bootcamps for data science can be taken by individuals already employed in the IT industry. Bootcamps are designed to give students hands-on experience using cutting-edge technologies, and many companies offer paid internships at various IT companies upon completion of the course. Some bootcamps even offer paid industry-exclusive courses on topics related to big data and analytics. Other courses teach students how to use databases, web applications, and visualization technologies to analyze and visualize data.

If you’re already in the IT industry or planning to enter the IT industry to shift your career, you can enroll in Clarusway’s data science course, which helps you to get data science or data analytics jobs.

Especially in the last 50 years, many software languages ​​have been developed and the technologies used are changing every day. On the other hand, companies are rapidly searching for experienced personnel with valid SQL certification.

Because SQL is used extensively in all software processes, it is also indispensable for analysts who will generate meaningful information from the available data. In addition, the transfer of data to the database and database development process is completely carried out by SQL Developers.

So, I can hear you ask, how can I learn SQL? I can say that you are in exactly the right place for this.

In this article, in which I aim to introduce SQL to you, I will explain different SQL concepts and guide you to quality educational content. Enjoy…

History of SQL

Developed for the first time in the early 1970s by IBM engineers Donald Chamberlin and Raymond Boyce, SQL was designed to access and intervene data stored in System R, the first relational database management system used in the IBM research lab.

Relational Software INC at the end of the 1970s (Oracle) recognized the importance of SQL, developed its own SQL-based RDBMS, and released the first SQL Oracle V2 version in 1979.

Not wanting to lose its competitive power in the market, IBM introduced the SQL database systems named System / 38, SQL / DS, and DB2 as a commercial product in 1979 and the following years.

Subsequently, SQL became a standard of the American National Standards Institute (ANSI) in 1986 and the International Organization for Standardization (ISO) in 1987.

Relational Database Concepts

Before I talk about what SQL is, I will have to explain some concepts.

Let’s start with the data concept first. Data = information. Especially with the invention of writing, the knowledge and experiences of human beings started to be recorded for later use. The information recorded and used with traditional means until the 20th century has now been transferred to digital platforms. This technology slightly changed the meaning of information, and information has now begun to be called data.

Today, all companies, small or large, work with different types of data that concern them. Most people who are just starting to work with data will do this using a spreadsheet. Some software such as Microsoft Access can be used to process and analyze data. However, as the volume and complexity of the data you are working on increases, these tools can become inefficient.

At this point, the relational database (RDBMS) concept emerges.

Relational databases, as the name suggests, refer to data storage structures in which multiple entities are in a certain relationship with each other. A Relational Database Management System (RDBMS) is a system used to manage relational data. Popular RDBMSs include Microsoft SQL Server, MySQL, and Oracle

What is SQL?

Here, we finally get to the subject of what SQL is. SQL has been developed to manage the above-mentioned relational database systems to generate and recall the required information.

SQL, which was first developed as SEQUEL (Structured English Query Language), was later called SQL (Structured Query Language) due to commercial usage restrictions.

Although there are minor usage differences, SQL appears with the same query words in all RDBMSs. Apart from this, while PL / SQL is used as a customized SQL programming language in Oracle DBMS, a programming language called Transact SQL or T-SQL is used in MS SQL Server DBMS.

RDBMSs work with related and normalized table structures that mostly store structured data. Structured data are ones that have been organized according to a consistent structure. Therefore, structured data can be easily arranged in tables. Thanks to its consistent organization, it is easier to work with structured data that can be processed more effectively.

For example, consider the following table:

Each row has a clear relationship; a particular staff member gets a job in a particular department and receives a specific salary. Columns are also known as fields, rows are known as records.

SQL Language

In SQL, a query is created using different command words. According to their intended use or case of joint use, these commands are classified as sub-languages ​​of SQL, which we will examine below.

Data Definition Language (DDL):

DDL commands are used to define a table, a database, or any database object. CREATE, ALTER, DROP and SELECT INTO count as SQL commands in this category.

Data Manipulation Language (DML):

DML commands are used when you need to update data or perform calculations or operations on it. INSERT, UPDATE, MERGE and DELETE count as SQL commands in this category.

Data Control Language (DCL):

If you want to do some authorization or control operations such as allowing or denying some actions on the data, you should work with DCL commands that include GRANT and REVOKE commands.

Transaction Control Language (TCL):

Anything that changes the data is called Transaction. When a transaction occurs, the changes are first applied to data in the temporary location. TCL commands are used to replace the data in the database itself with data at this temporary location or reverse the transaction. It is the TCL command used to complete COMMIT Transactions. On the other hand, ROLLBACK is the TCL command used to prevent the applied transactions to the original data and reverse the transaction.

Data Query Language (DQL):

This final SQL concept consists of the SELECT command used to retrieve data from the database.

Why is SQL Preferred for Data Analysis?

Although engineers widely use SQL in software development, it is also popular among data analysts because it is semantically easy to understand and learn.

Daily Usage of SQL

Imagine that you’re looking for a movie or actor to your liking on Netflix. You can take advantage of the categories or the search bar in the menu. Here, as you browse an application like this, SQL is responsible for returning the information you “request” each time you click a link. Because it is not in sight, SQL is always in the role of a hidden hero.
