The term “Big Data” refers to the continuing massive expansion in the data
volume and diversity as well as the speed and complexity of data processing.
The use of big data underpins critical activities in all sectors of our
society. Achieving the full transformative potential of big data in this
increasingly digital world requires both new data analysis algorithms and
a new class of systems to handle the dramatic data growth, the demand to
integrate structured and unstructured data analytics, and the increasing
computing needs of massive-scale analytics.
