meta data for this page

My definition to Big Data:

Big Data refers to a huge amount of data, which can be used to find correlations between various things. Data is so big that it doesn't fit to regular structured databases or cannot be handled with regular tools. You have to find alternative way to process big data. Analysis of big data answer question what, not why.
