Data science, in simple terms, is drawing useful insights from structured or unstructured raw data. The objective of this article is to provide you with the knowledge you require to understand the benefits of data science, its implementation in several businesses, jobs available for data scientists and courses available to become one. 

What is data science?

Data science is the process to draw information from raw data and interpret it into useful insights for business decisions. Different businesses use data science everyday to develop new patterns related to their business which help the company grow.

Data science involves a life cycle of capturing, maintaining, processing, analysing and then communicating. To elaborate this lifecycle; First raw data is captured from different sources, it is then converted into useful form, then processing it which involves data mining, data modelling, data classification and summarization to find patterns and ranges for analysis, then performing different analyses using several methods and lastly communicating the analyses in comprehensible forms.

what does data science do
Data Science
The work involved in data science from analysing data to forming a pattern, which helps in business decision making.

Benefits of data science?

Data science binds IT and management together. By structuring data by predictive analyses, Data science has made business decisions more definite, calculative and customer oriented. There are various benefits of data science few of which are listed below:

  • Data science is flexible in terms of demand, it is used in major sectors like healthcare, e-commerce, finance, corporate and more, making it one of the eminent jobs.
  • Data science helps businesses to make better decisions.
  • It lowers business risks with data-driven evidence that helps in calculative actions.
  • Data science helps in sales and marketing by providing solutions based on customer experiences and expectations.
  • It works on the current work system to analyse the system for improvements.
  • The job also includes developing patterns and algorithms to develop the management and products.
  • Data science uses machine learning and Artificial intelligence which helps in developing security and automation.

Eligibility, Job opportunities and salary benefits of data science

We have discussed the basics of data science and how it is beneficial for businesses. Let us now discuss how it is beneficial for an individual, what are the opportunities available and how it is an advantageous career.

Eligibility for learning data science courses

Data science requires knowledge of mathematics and statistics, computer science is an added advantage. For undergraduate students, it requires more than 50% marks in mathematics, statistics or computer science in 12th examination.

For graduates, it requires a bachelor’s degree in science, engineering, technology or mathematics. Graduates in business studies like BBA or MBA, are also eligible for suitable data science courses

To sum up, any professional belonging to IT, marketing, engineering or software can take a data science program or course to pursue a career in the fields of data science

Job opportunities after completion of a data science course

Data science is a vast field with many job opportunities and is the fastest growing job in Linkedin, which is expected to create 11.6 million jobs by 2026. In comparison to IT fields, data science has high demand for professionals as there is less availability in the sectors. According to an article published in naukri.com, 3,00,000 plus data scientists would be required in different sectors by 2024, with 3400 positions increasing every month. These sectors include healthcare, banking, finance, media and entertainment, retail, telecommunications, automobile and others.

Salary benefits after data science

According to U.S. news, in the USA Data scientists made an average of $98,230 in 2020. The highly paid 25% made $130,370 and the less paid 25% made $71,790 in that year. As per PayScale, the average salary for data scientists in India is Rs. 812,954. The top companies paying higher salaries in India are Amazon, Flipkart, Walmart, Hewlett Packard Enterprise, IBM, Deloitte Accenture and [24]7.ai.

Curriculum of data science?

The curriculum of data science depends on the experience of an individual. It is divided into three parts based on the experience level or knowledge of an individual. These are; basic, intermediate and advanced courses in data science with relevant certifications.
