We live in a data-driven world. In fact, the amount of digital data that exists is growing at a rapid rate, doubling every two years, and changing the way we live. Now that Hadoop and other frameworks have resolved the problem of storage, the main focus on data has shifted to processing this huge amount of data. When we talk about data processing, Data Science vs Big Data vs Data Analytics are the terms that one might think of and there has always been a confusion between them.

In this article on Data science vs Big Data vs Data Analytics, I will be covering the following topics in order to make you understand the similarities and differences between them.

Introduction to Data Science, Big Data, & Data Analytics

Let’s begin by understanding the terms Data Science vs Big Data vs Data Analytics.

What Is Data Science?

Data Science is a blend of various tools, algorithms, and machine learning principles with the goal to discover hidden patterns from the raw data.

It also involves solving a problem in various ways to arrive at the solution and on the other hand,  it involves designing and constructing new processes for data modeling and production using various prototypes, algorithms, predictive models, and custom analyses. You can also predict the growth of the business by incorporating data science techniques in operations in the coming years, anticipate the potential for problems, and develop strategies based on data to achieve success. This is the best opportunity to kick off your career in the field of data science by taking the Data Science Course.


What is Big Data?

Big Data refers to the large amounts of data that is pouring in from various data sources and has different formats. It is something that can be used to analyze the insights which can lead to better decisions and strategic business moves.

What is Data Analytics?

Data Analytics is the science of examining raw data with the purpose of drawing conclusions about that information. It is all about discovering useful information from the data to support decision-making. This process involves inspecting, cleansing, transforming & modeling data.

What Does Data Scientist, Big Data Professional & Data Analyst Do?

What does a Data Scientist do?

Data Scientists perform an exploratory analysis to discover insights from the data. They also use various advanced machine learning algorithms to identify the occurrence of a particular event in the future. This involves identifying hidden patterns, unknown correlations, market trends and other useful business information.

What do Big Data Professionals do?

The responsibilities of big data professional lies around dealing with huge amount of heterogeneous data, which is gathered from various sources coming in at a high velocity.

                                                      Roles of Big Data Professional

Big data professionals describe the structure and behavior of a big data solution and how it can be delivered using big data technologies such as Hadoop, Spark, Kafka etc. based on requirements.

What does a Data Analyst do?

Data analysts translate numbers into plain English. Every business collects data, like sales figures, market research, logistics, or transportation costs. A data analyst’s job is to take that data and use it to help companies to make better business decisions. Data Analyst Course will help you to become a certified Data Analyst.

A Scenario Illustrating The Use Of Data Science vs  Big Data vs Data Analytics.

Now, let’s try to understand how can we garner benefits by combining all three of them together.

Let’s take the example of Netflix and see how they join forces in achieving the goal.

First, let’s understand the role of Big Data professionals in Netflix’s example.

Netflix generates a huge amount of unstructured data in form of text, audio, video files, and many more. If we try to process this dark (unstructured) data using the traditional approach, it becomes a complicated task.

    Traditional Data Processing              Approach in Netflix

Hence a Big Data Professional designs and creates an environment using Big Data tools to ease the processing of Netflix Data.

Now, let’s see how Data scientists Optimize the Netflix Streaming experience.

                 Role of Data Scientist in Optimizing the Netflix streaming experience

1. Understanding the impact of QoE on user behavior

User behavior refers to the way how a user interacts with the Netflix service, and data scientists use the data to both understand and predict behavior. For example, how would a change to the Netflix product affect the number of hours that members watch? To improve the streaming experience, Data Scientists look at QoE metrics that are likely to have an impact on user behavior. One metric of interest is the rebuffer rate, which is a measure of how often playback is temporarily interrupted. Another metric is bitrate, which refers to the quality of the picture that is served/seen — a very low bitrate corresponds to a fuzzy picture. Learn more about Big Data and its applications from the Azure Data Engineering Certification in India.

2. Improving the streaming experience

How do Data Scientists use data to provide the best user experience once a member hits “play” on Netflix?

One approach is to look at the algorithms that run in real-time or near real-time once playback has started, which determine what bitrate should be served, what server to download that content from, etc.

For example, a member with a high-bandwidth connection on a home network could have very different expectations and experiences compared to a member with low bandwidth on a mobile device on a cellular network.

By determining all these factors one can improve the streaming experience.

3. Optimize content caching

A set of big data problems also exists on the content delivery side.

The key idea here is to locate the content closer (in terms of network hops) to Netflix members to provide a great experience. By viewing the behavior of the members being served and the experience, one can optimize the decisions around content caching.

4. Improving content quality

Another approach to improving user experience involves looking at the quality of content, i.e. the video, audio, subtitles, closed captions, etc. that are part of the movie or show. Netflix receives content from the studios in the form of digital assets that are then encoded and quality checked before they go live on the content servers.

In addition to the internal quality checks, Data scientists also receive feedback from our members when they discover issues while viewing.

By combining member feedback with intrinsic factors related to viewing behavior,  they build the models to predict whether a particular piece of content has a quality issue. Machine learning models along with natural language processing (NLP) and text mining techniques can be used to build powerful models to both improve the quality of content that goes live and also use the information provided by the Netflix users to close the loop on quality and replace content that does not meet the expectations of the users.

So this is how Data Scientist optimizes the Netflix streaming experience.

Now let’s understand how Data Analytics is used to drive the Netflix success.

                                          Role of Data Analyst in Netflix

The above figure shows the different types of users who watch the video/play on Netflix. Each of them has their own choices and preferences. 

So what does a Data Analyst do?

Data Analyst creates a  user stream based on the preferences of users. For example, if user 1 and user 2 have the same preference or a choice of video, then data analyst creates a user stream for those choices. And also – 

  1. Orders the Netflix collection for each member profile in a personalized way.
  2. We know that the same genre row for each member has an entirely different selection of videos.
  3. Picks out the top personalized recommendations from the entire catalog, focusing on the titles that are top on ranking.
  4. By capturing all events and user activities on Netflix, data analyst pops out the trending video.
  5. Sorts the recently watched titles and estimates whether the member will continue to watch or rewatch or stop watching etc.

I hope you have understood the differences & similarities between Data Science vs Big Data vs Data Analytics.
