Is the process and methodology through which data scientists draw useful insights by manipulating data. They gather, organize, analyze, and turn the raw data into intelligibly visualized information to assist and augment our decision-making abilities, which is not possible without an efficient record-keeping or data-generating system.

When the data is huge that exceeds our comprehension capacity in terms of structure and power, that is where modern computing and analytical constructs come into the frame. That is Data Science.
