RATIONALE: Big data is a term used to describe data collections that are so enormous (think petabytes or larger) and complex (from sensor data to social media data) that traditional data management software, hardware, and analysis processes are incapable of dealing with them. To provide perspective on just how much data a petabyte is, consider that one petabyte of storage could contain 50 years’ worth of high-quality video.
