Big data
Big Data is the digital trace that we are generating in this digital era, as shortly defined by Bernard Marr.
This digital trace is made up of all the data that is captured when we use digital technology.
More extensively, Gartner defined Big Data as:
High-volume, high-velocity, and/or high-variety information assets that demand cost-effective, innovative forms of information processing that enable enhanced insight, decision making and process automation.
