Data science is an interdisciplinary field that uses scientific methods, processes, algorithms and systems to extract knowledge and insights from many structural and unstructured data.
Data science is a "concept to unify statistics, data analysis 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, statistics, computer science, domain knowledge and information science.
It is the domain of study that deals with huge data using modern tools and techniques. It finds unseen patterns, derives meaningful information, and makes room for optimal business decisions. Data science uses machine learning algorithms or AI algorithms to build predictive models.
