Big data is a term used to describe the voluminous(Occupying
or containing much space; large in volume, in particular )amount of unstructured
and semi-structured data a company organization
creates -- data that takes too
much of time and cost to load a relational database for analysis and implement. Although Big data is not refer to
specific quantity of data.
Moto for looking at big data is to discover and invent repeatable
business patterns. It’s mainly accepted that unstructured data, most of it located in
text files and we all know what is text file is , accounts for at least 80% of
an organization’s data. If left unmanaged, the sheer(extra ordinary) volume of unstructured data that is
generated yearly within an enterprise or
organization can be costly in terms of storage of Data. Unmanaged data
can also pose a liability if information cannot be located.
Big data is often associated with cloud computing because the analysis of large data world in real-time requires a framework like MapReduce to
distribute the work among tens, hundreds or even thousands of computers.
