What is Big data?
“Big data” refers to datasets whose size is beyond the ability of typical database software tools to capture, store, manage, and analyze.
This definition is intentionally subjective and incorporates a moving definition of how big a dataset needs to be in order to be considered big data—i.e., we don’t define big data in terms of being larger than a certain number of terabytes (thousands of gigabytes).
We assume that, as technology advances over time, the size of datasets that qualify as big data will also increase. Also note that the definition can vary by sector, depending on what kinds of software tools are commonly available and what sizes of datasets are common in a particular industry. With those caveats, big data in many sectors today will range from a few dozen terabytes to multiple petabytes (thousands of terabytes).
What do we mean by "big data"?

The volume of data is growing at an exponential rate
The intensity of big data varies across sectors but has reached critical mass in every sector
Major established trends will continue to drive data growth
Traditional uses of it have contributed to productivity growth — big data is the next frontier

big data creates value in several ways
While the use of big data will matter across sectors, some sectors are poised for greater gains
Big data offers very large potential to generate value globally, but some geographies could gain first
There will be a shortage of the talent organizations need to take advantage of big data
Several issues will have to be addressed to capture the full potential of big data
