### Data Science

#### What is Data Science?

Data Science refers to the process of mining, inspecting, cleansing, and modeling data in order to reveal useful insights and information that would have otherwise been unobtainable. Most organizations that make analysis an integral part of their day-to-day operations use the conclusions suggested by the data to make informed business decisions.
Data science is a "concept to unify statistics, data analysis, machine learning and their related methods" in order to "understand and analyze actual phenomena" with data. It employs techniques and theories drawn from many fields within the context of mathematics, statistics, information science, and computer science.
