what does it mean BIG DATA ?

Big data is a broad term for data sets so large or complex that traditional data processing applications are inadequate. Challenges include analysis, capture, data curation, search, sharing, storage, transfer, visualization, and information privacy. The term often refers simply to the use of predictive analytics or other certain advanced methods to extract value from data, and seldom to a particular size of data set. Accuracy in big data may lead to more confident decision making. And better http://www.stibosystems.com/solution/multidomain-mdm decisions can mean greater operational efficiency, cost reduction and reduced risk.

Relational database management systems and desktop statistics and visualization packages often have difficulty handling big data. The work instead requires "massively parallel software running on tens, hundreds, or even thousands of servers". What is considered "big data" varies depending on the capabilities of the users and their tools, and expanding capabilities make big data a moving target. Thus, what is considered "big" one year becomes ordinary later. "For some organizations, facing hundreds of gigabytes of data for the first time may trigger a need to reconsider data management options. For others, it may take https://www.youtube.com/watch?v=fH03Rj4O0PU&index=1&list=PL6b-Dl60taJxI8rnHuGaa88Bw7teMYMIn tens or hundreds of terabytes before data size becomes a significant consideration."

I found this really well written article, hope it helps
