What is BIg Data?

Is it some technical term to define data or some processing application or some new things in the internet world?

In common, we can say that it is massive store of data. It might be petabytes or exabytes of data.

It is a combination of structured and unstructured data and too large to manipulate and manage. Traditionally structured data can be managed with the help of data processing application RDBMS but what about of unstructured data.

One report says that 92% of total data present till date is created in last 2-3 yrs.

Now questions arise

         1. Where from this mass of data is coming and generating?

       2.  Is static data or dynamic data?

         3. How and why did the term Big Data come into the picture and who applied this term?

Today we have social sites/media, online shopping/trade, Customer contact center, Mobile media etc.From these sources data are generating at a speed of light (if we have to say).These data are not small data and not even erasable and its size is beyond the capacity of software tool to capture, manipulate, store and manage because our traditional processing tool has limitations.
