Big Data
7.1 Definition
There are several definitions of Big Data, with the most commonly used
referring to large volumes of data beyond the normal processing,
storage and analysis capacity of typical database application tools.
Although Big Data does not refer to any specific quantity, the term is
often used when speaking about petabytes and exabytes of data.
The definition can be extended to incorporate the variety of types of
data involved. Big Data will often include much more than simply
financial information and can involve other organisational data which is
operational in nature along with other internal and external data which is
often unstructured in form.
