Data

Data science is an interdisciplinary academic field that uses statistics, scientific computing, scientific methods, processes, algorithms and systems to extract or extrapolate knowledge and insights from noisy, structured and unstructured data. Data science also integrates domain knowledge from the underlying application domain (e.g., natural sciences, information technology, medicine). Data science is multifaceted and can be described as a science, as a research paradigm, as a research method, as a discipline, as a workflow, and as a profession.Data science is a "concept to unify statistics, data analysis, informatics, and their related methods" in order to "understand and analyse actual phenomena" with data. It uses techniques and theories drawn from many fields within the context of mathematics, statistics, computer science, information science, and domain knowledge. However, data science is different from computer science and information science. Turing 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.
