What is Data Science?
Data science is an umbrella term in which many scientific methodologies apply such as mathematics, statistic, programming languages etc. It is a data driven science applied to extract facts from raw data with an associative match of data inferences, algorithms development and technology for solving analytically difficult problems.
Data Science Overview
Data science is a challenging and engaging task as it demands more comprehensive understanding of facts. It helps to solve and tackle data science problems in general and requires critical thinking as it is related to problem solving skills.
Data science in real time deals with various tools such as R, python and Excel which are used in drawing graphical representation through which one can make fair decision about the progress and make the further improvements if necessary.
