science is a multidisciplinary approach towards gaining valuable
insights from Big data. These insights help an organization in improving
its operations and making efficient and intelligent decisions. It makes
use of techniques like Machine learning, Cluster analysis, Data mining,
Visualization and employs the field of Mathematics and statistics.
Why Data Science?
every passing day, the amount of Big Data is increasing giving rise to
the requirement of management and processing of this Big data and Data
science gains its importance from this requirement. With 2.5 quintillion
bytes being produced every day, the skill of organizing this set gives
one an added advantage. Companies like Google, Facebook, Microsoft are
looking for experts, increasing the job vacancies in the field. The
influence of Data science is across all major industries like
healthcare, finance, retail, chemical, agriculture, media etc.
