Big data is not defined by how you can measure data in terms of volume, velocity, and variety. The three Vs are just measures of data— how much, how fast, and how diverse?

Exponential data growth makes it continuously difficult to manage — store, process, and access.
Data contains nonobvious information that firms can discover to improve business outcomes.
