What is Data Science?

Data science is a field where an individual uses multiple but interrelated academic disciplines such as computer science, mathematics, statistics principles, analytics, data visualization, and programming to pull out knowledge and insightful data from various available scattered data to provide the solution.

The individual who is qualified or skilled to work on such data to provide solutions is called a Data Scientist.

The data scientists use various scientific methods, principles, and systems to show the outcome of such analysis to solve problems.  They uses structural as well as unstructured data for analysis.

In a more simple word, data science is all about applying multiple methods on some available data to take out very deep insightful data that can solve current as well as future problems. The data science mainly helps to make predictions based on data and look for solutions.

I hope now you have some idea about Data Science & Data Scientist.

There is a difference between Data Scientist vs. Data Analyst
