Data science is a "concept to unify statistics , data analysis , informatics , and their related methods" in order to "understand and analyze actual phenomena" with data. It uses techniques and theories drawn from many fields within the context of mathematics ,computer science , statistics , information science , and domain knowledge . However, data science is different from computer science and information science. Turning Award winner Jim Gray imagined data science as a "fourth paradigm" of science (empirical , theoretical , computational , and now data-driven) and asserted that "everything about science is changing because of the impact of information technology " and the data deluge . A data scientist is someone who creates programming code, and combines it with statistical knowledge to create insights from data. Data science is an interdisciplinary field focused on extractin...
