Today, people and systems overload the web with an exponential
generation of huge amount of data. The amount of
data on the web is measured in exabytes (1018) and zettabytes
(1021). By 2025, the forecast is that the Internet will exceed
the brain capacity of everyone living in the whole world [1].
This fast growth of data is due to advances in digital sensors,
communications, computation, and storage that have
created huge collections of data.1 The term Big Data had been
coined, by Roger Magoulas (according to [2]), to describe this
phenomenon.
