Before the starting of the 21st century, the world had already developed it all from industries to huge machines, to computers and mobile phones. Now what is left for us is a huge pile of data. By 2020, the data created is estimated to be 40 trillion gigabytes. This data gave rise to Data Science which is used to predict and stimulate for future references. The data which started only from bits has now reached to astronomical values.
What is Data Science?
Data science is a group of techniques used to extract values from the data. It is a multi-disciplinary field that uses algorithms, programming skills, knowledge of maths and statistics, data analysis, information science and computer science to extract the data. Every company and organization uses data science to collect and analyze their data.
Cleveland in 2001 said, “One outcome of the plan is that computer science joins mathematics as an area of competency for the field of data science. This enlarges the intellectual foundations.” Hence, Data Science can be referred to as a combination of Mathematics, Computer Science and Business Intelligence (BI).
Role of a Data scientist
Data Scientist is a person who makes values out of the data. Their main purpose is to form and analyze big data. Role of the data scientist in various industries is as follows.
- Big data analytics: Data scientists analyze big data using predictive modelling, developing segmentation algorithms, etc.
- Finance: Role of a data scientist is to study the impact of specific financial trends and market development by taking into account customer’s financial data
- Banks: Banks take the help of data scientist in customer service, fraud detection, target marketing, understanding customer sentiments, etc.
- Healthcare: They interpret data by using computerized medical records, billing claim, cost reports, etc.
How to become Data Scientists?
To become a data scientist, the qualification required is as follows:
- Bachelor’s degree in IT, computer science, maths, physics, statistics, engineering
- Master’s degree in Data Science or other related fields
You can also do certification courses in Data science like MCSE by Microsoft in Data Science which will be beneficial to you in the long run. The average salary of a data scientist is 10 lakh in India and $ 100K worldwide.
