Data science is a multi-disciplinary field that uses scientific methods, processes, algorithms and system to extract knowledge and insights from structured and unstructured data.[1][2] Data science is the same concept as data mining and big data: “use the most powerful hardware, the most powerful programming systems, and the most efficient algorithms to solve problems".
