What is Data Science?: Course, Career, and Salary Overview

What is Data Science?

Data is the oil of the 21st century, says Hal Varian, Chief Economist at Google. Data Science is now increasingly used in financial services, healthcare, retail, education, and even in security and governance. It is the comprehensive study of making use of tools like mathematics and statistics, Artificial Intelligence, specialized programming, advanced analytics, and machine learning to extract knowledge and insights from both structured and unstructured data. A data scientist’s role is the “sexiest job of the 21st century” by Harvard Business Review. He is the one who creates programming codes to interpret data for the betterment of the organization. Data science courses teach the fundamentals of analyzing data, performing analyses, and understanding and communicating actionable insights. Students from the fields of science, technology, engineering, and mathematics (STEM) are eligible to pursue data science courses. This article highlights everything you want to know about the Top 5 Data Science courses in India, their details, careers, and salary packages.

History of Data Science

Data Science primarily includes three aspects:- Data design, collection, and analysis. The term Data Science was first introduced in the 1960s as an alternative term for Statistics. Computer Science professionals came with this new name in the 1990s. Later on, statisticians coined this term as the application of traditional statistics. Since then, data science has been evolving to make useful predictions and gain insights into a wide range of fields like astronomy, medicine, business, etc using computer science and statistical methodology.

What are the different tools of Data Science?

A data analyst or a data scientist requires so many tools to gather insights from raw and unclassified data. Microsoft Excel is the most commonly used platform for data analysis and interpretation. Excel provides many user-friendly features like its built-in Pivot Table sharing workbooks, etc. Analysts can easily create Data Aggregation and represent the data visually pleasingly. Apart from Microsoft Excel, the following tools are most commonly used by them in this process.

  • R and Python
  • Microsoft Excel
  • Tableau
  • RapidMiner
  • Power BI
  • Apache Spark
  • QlikView
  • Talend
  • Splunk

Why Data Science Course?

With an overall hike in the demand for Data Scientists in India, many educational institutes in the country have come forward with integrated Data Science Courses along with their academics. The main focus of the course is to build knowledge among the aspirants about machine learning, regression analysis, design and analysis of algorithms, data visualization, application of data science tools in business analytics, and so on.

The evolution of Data Science can be traced from being only analytics and statistics to decisions, predictions, and actions that move the world. During the pandemic, the volume of data increased unexpectedly and that too needed to be structured and analyzed. Hence, job openings in this field have also been tremendously increased. In 2021 alone, Glassdoor shows around 37,000 data science jobs are available in the country, including machine learning engineers, data analysts, business analysts, and financial analysts. Data scientists with excellent expertise in advanced technical skills and in programming languages are high in demand and more likely to get recruited for higher-paying positions. MNCs like Amazon, Deloitte, LinkedIn, Flipkart, IBM, and Accenture offer plenty of Data Science jobs.

There are plenty of data science careers. Let us look at some of them: 

Data Scientist

Unlike Data Scientists, data analysts use structured data to solve business problems. Using Data Science tools such as SQL, Python, R, and the like, data analysts acquire, process, and reorganize data for analysis to find trends that can be turned into business insights. A Data Analyst translates findings into reports and makes them understandable to the management, thus helping them in decision making. 

Average annual salary in India : ₹ 4.3 LPA

Average annual salary in US: $63,344 

Data Architect

The main role of a Data Architect is to train employees for gaining access to information whenever they need it. Data architect designs plan in order to process all kinds of data sources. He also develops application programming interfaces (APIs) to retrieve data. Moreover, he translates business requirements into databases. Collaborating with other teams within the organization, he implements data strategies, builds models, and assesses shareholder needs and goals. 

Average US Salary: $115,196

Salary in India: ₹13.5-23.5 LPA

Business Analyst

 It is the primary role of a business analyst to identify any issue associated with the organization. For that purpose, they constantly evaluate past and present business data and help in decision-making. 

Average Salary in US: $74,366

Average Salary in India: 7.0 LPA

Project Manager

As the name implies, a Project Manager oversees the execution of the project and gives suggestions. The different stages in the process like data mining, extraction, testing, analysis, and application for creating a blueprint require proper management by a team led by the Project manager. The Manager acts as a link between the team and clients to communicate requirements and changes in the project.

Average Annual Salary in India: ₹ 14.5 LPA

Average Annual Salary in US: $81,315

Some of the other designations are R Programming Trainer, Lead Python Developer, Al and Machine Learning Expert, ML Specialist, Python Programmer-Machine Learning, Lead Data Scientist, Data Scientist Developer, Data Engineer, Applied Data Scientist, etc.


Online marketing and entertainment giants like Amazon and Netflix are largely dependent on Data Science to get consumer insights. Experts believe and foresee Data Science as the most predictive skillset that has largely helped organizations to obtain meaningful insights from unstructured and raw data. 

Data Science Courses are in high demand these days. With the certification courses and years of work experience, students can explore different domains like marketing, sales, data quality, finance, business intelligence, etc., and even work as consultants with leading data-driven firms.
