Dear student,

Thanks for posting your query on CareerGuide.com.

How do you take a decision? Most people consider their past experiences, guage future possibilities, weigh the pros and cons of the situations and possible outcomes and take a decision accordingly.

In the work of business, this is what data scientists help to do.

Data science is the use of many techniques to derive meaning from relevant data that often drive business decisions. Therefor it is sometimes also alled as business analytics.

Most of the times it is a combination of maths, statistics, advanced computing, data mining, visualisations and modeling that is used to do this job.

The insights derived from data using such multidimensional techniques are used in multidisciplinary areas such as cloud computing, database integration, language processing, business development, risk management, organisational development, etc.

It is also used in security and fraud monitoring,as in the case of internet usage where huge amounts of usage data is analysed to uncover possible security risks and insider threats.

Data scientists could work in any field like banking, e-commerce, insurance, healthcare and the retail sector. For example by looking at the pattern of buying of the present youth, retail companies can develop new products according to thier needs and preferences. FOr this they would require a data scientist.

Similarly, websites like Facebook, Twitter, and companies like Microsoft etc hire data scientists to analyse their clients' usage data to identify areas where they can modify or improve their product or service.

Data scientists were also employed in large Government project like the UIDAI Adhaar project where they had to manage very very huge amounts of biometric data of crores of citizens.

Thus applications of the skills and expertise of data scientists are immumerable. In today's world, they can be an asset for any field.

Hope this information help.
