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 extracting knowledge from data sets, which are typically l
