Data Science 2020: Evolution and Key Applications.

For anyone who is actively involved in the tech world, the term “Data Science” shouldsurely sound quite familiar. Data Science technology has positively impacted various aspects of our day to day life in many ways, such as finding the most affordable gifts or items while shopping online or while booking a movie ticket by comparing prices and reviews across different websites and apps – just to name a few.

As more and more data is being generated every day, it is creating new challenges as well as opportunities for tech enthusiasts.

Do you know how much data is generated every day on this planet?

Before getting to that, let us first check the number of active Internet users we have in this world. As per the report provided by Internet live stats, in 2014,  around 2.4 billion people  accessed the Internet and that number kept growing continuously. In the year 2016, we had around 3.4 billion users.  Reports suggest that as of 2019, the number of active Internet users has reached  4.4 billion.

According to a report, from the last 5 years, on average, 640,000 people per day went online for the first time. This was about 27,000 every hour. Incredible, isn’t it? With all these stats, we can understand why so much  data is getting generated every day.

As per the available data from, around 3.5 billion searches are made on Google alone and about 281 billion emails are being sent and received each day. Nearly 5787 tweets are made every second, which adds up to 500 million tweets per day. In YouTube, nearly 5 billion videos are watched every day and up to 300 hours of videos are uploaded every minute. An estimate says that around 2.5 quintillion bytes of data is being generated every day.

Now we hope that you got the answer to the above question. These are quite big numbers, aren’t they?

All this data is a goldmine of information and intelligence hidden within it. The challenge, however, is how to meaningfully make  sense of the data at this scale and volume. This is where Data Science has its role to play. Data Science can help us to make sense of the data at this scale and make smarter predictions/decisions with the kind of precision which was never heard of earlier. As the saying goes:

Data is the new oil for all the industries and data science is the electricity that powers the industry!

This makes Data Science  a very important field, which places  its professionals in high demand. Harvard Business Review has even called it “The Sexiest Job of the 21st Century”.

Now let us define Data Science:

Data Science is a multi-disciplinary field that applies scientific methodologies to extract meaningful information from billions and trillions of bytes of structured and unstructured data. It employs concepts and methods drawn from the fields of mathematics, statistics, computer science and information science.

Data Science has become a buzzword, it is interchangeably used with Data Mining and Big Data.

In simple terms, Data Science can be understood as the study of data. It involves developing various methods of recording, storing and analyzing data to effectively extract useful information.

Evolution of Data Science

Data Science emerged with the use of statistics: an idea to use data better and to find better solutions for problems.

In earlier days, say in the 1800’s, simple statistical methods were employed to collect, analyze and manage the data. These statistical models were used to recognize patterns, model and visualize uncertainty and predict the future of data.

Later, with the emergence of industries across different segments, these statistical methods eventually evolved into Operations Research: a discipline that applies scientific methods and modern technologies to organize data efficiently, enabling  larger enterprises to make better decisions for their business enhancement.

With further advancements in technologies, different algorithms and techniques, such as Data Analysis, started to evolve, and in a way led to the growth of Data Science.

In the 1970’s, the world gradually entered into the Digital Age. During this period, IBM introduced personal computers to the mainstream public, which led to the advancement of the digital world, resulting in the availability of a large amount of data from different sources. Thus, new technologies increased in order to collect such data, store it systematically and manipulate it properly. As a result of these developments, statistics become computerized, leading to the emergence of new concepts such as Data Mining and Data Analytics.

In the later years, several mathematicians and Data Scientists published several journals and research papers on Data Science, in a way contributing to the growth of this wonderful field of technology.

We have tracked a few notable works in below discussion.

In the year 1974, Peter published Concise Survey of Computer Methods, where he used the term Data Science in its survey of contemporary data processing methods: a data processing method used in most of the applications.

In the year 1977, The International Association for Statistical Computing (IASC) was established as a section of ISI with a mission to apply modern technologies to convert data into information and knowledge.

In September 1994, Business Week published a cover story on “Database Marketing” in which it discussed how companies were collecting  information about their consumers and analyzing what kind of product they buy, which helped them to enhance their business growth.

In the year 2008, the term was Data Science was popularized by D. J. Patil and Jeff Hammerbacher, the pioneer leads of data and analytics efforts at LinkedIn and Facebook.

As the Internet started becoming the main source of gathering data, it also emphasized the importance of Data Science. Today, Data Science has evolved into an interdisciplinary field that can be used to analyze the large amount of data and extract valuable insights from it and help  businesses across many industries such as manufacturing, banking and finance, and retail, etc., to leverage their business.

This was a brief history of the evolution of Data Science. You can also read an article, “A Brief History of Data Science” to find some more information about Data Science history.

Working with Data Science:

Now that we know how this Data Science technology slowly evolved and became a mainstream technology,  let us look into some common steps involved in most of the Data Science projects. As the steps vary with each project, we discuss some of them that are most commonly executed in every project. These steps are as follows:

  • Understanding the problem
  • Getting the relevant Data
  • Data Cleaning
  • Data Visualization
  • Data Selection
  • Communication.

Now let us understand each of these steps individually.

  • Understanding the problem:

The first phase of any Data Science project is to understand the actual problem that you need to solve. Once you know what the issue is and what type of solution you need to provide, only then you can search the relevant data for it. So, understanding the problem is very important.

In order to understand the business problems, you need to work with your customer and stakeholders. Prepare a list of questions that define business goals which can be solved using Data Science.

  • Getting the relevant data:

After understanding the problem, the next step would be to start gathering the required Data much needed to able to find a solution for the problem. You can get this Data from different sources such as emails, applications, databases, servers, and many other services. Finding the right Data takes both time and effort. 

  • Data Cleaning:

Data Cleaning is a very important step. As per Data Scientists, they spend much of their time during the project in executing this step alone. This step involves cleaning and pre-processing the entire Data before feeding it to model. In some big projects, massive amount of Data has been obtained, which often involve terabytes of Data to work with. 

Different types of Data requires different types of cleaning. Some steps involved in cleaning data are removing unwanted observations i.e., duplicate and irrelevant observation, correct structural errors that arise during measurements, data transfer, and then handle missing data, etc.

  • Data Visualization:

Once the Data is cleaned and pre-processed, then it is important to visualize the data to find out the right features or columns to use for our model. Here you need to explore the Data and identify different types of Data like numerical data, categorical data, etc. Here, you can take help of simple charts such as bar charts or line charts that help you to understand the importance of Data.

This can be through the help of Data Visualization tools such as Tableau, Infogram, ChartBlocks. These tools help you to visualize all your data in very less time. They provide a pictorial representation of your Data that can viewers to easily understand the Data.

  • Model Selection:

This phase involves selecting the right model. Here, you will develop data sets for training and testing purpose. You need to check if the existing tools are enough to meet the requirements or you need some other better tools. This is necessary as every model cannot fit in perfectly for every data set. 

  • Communication:

Finally, now you need to evaluate if you were able to achieve your goal as per the plan. It is important to communicate the findings, in simple terms to the businessman, and to the stakeholders, as they are not expected to understand the technical know-how of Data Science.

The above discussed are a few common steps that every Data Scientist follows while working on Data Science projects. There are many additional helpful resources readers can access to understand about how Data Science projects work.
