Big Data as a concept is characterized by 3Vs: Volume, Velocity, and Variety. Big Data implies a huge amount of data. Due to the sheer size, Big Data tends to be clumsy.

Not just a handful of companies in the market merely collect lots of data with noise blindly, but they don’t know how to cleanse it, let alone how to transform, store and consume it effectively.
