2. Big data is a collection of problems that test the limits of
current IT and computational technologies, as well as
existing algorithms.
Big data is traditionally described as a large volume of
data (in excess of 1 terabyte) processed at a high rate
with a high degree of variety and veracity
The vast amount of data – both structured and
unstructured – that inundates a company on a daily basis
is referred to as big data. What counts is what companies
do with the data. Big data may be analysed for
perspectives that contribute to stronger business choices
and strategic steps.
