2003, humankind generated five
exabytes of data. Now we produce five
exabytes every two days…and the
pace is accelerating.

5. The basic idea behind the
phrase 'Big Data' is that
everything we do is increasingly
leaving a digital trace (or data),
which we (and others) can use
and analyse.
Big Data therefore refers to our
ability to make use of the ever-
increasing volumes of data.
With the datafication comes big
data, which is often described
using the four V’s:
• Volume
• Velocity
• Variety
• Veracity
