Data Science is an
interdisciplinary field about
processes and systems to
extract knowledge or
insights from data, which is
a continuation of some of
the data analysis fields such
as statistics, data mining,
and predictive analytics,
similar to Knowledge

encompasses a wide variety of
tools, applications and
methodologies that enable
organizations to collect data
from internal systems and
external sources; prepare it for
analysis; develop and run
queries against that data; and
create reports, dashboards and
data visualizations to make the
analytical results available to
corporate decision-makers, as
well as operational workers.

Big data is a term used to
refer to data sets that are
too large or complex for
traditional data-processing
application software to
adequately deal with.
It’s what organizations do
with the data that matters.
Big data can be analyzed
for insights that lead to
better decisions and
strategic business moves.
