Big data is a buzzword, or catch-phrase, meaning a massive volume of both structured and unstructured data that is so large it is difficult to process using traditional database and softwaretechniques. In most enterprise scenarios the volume of data is too big or it moves too fast or it exceeds current processing capacity.

According to wikipedia

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, sharingstoragetransfervisualizationquerying andinformation privacy. The term often refers simply to the use of predictive analytics or certain other 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 decisions can result in greater operational efficiency, cost reduction and reduced risk

Big data refers to a process that is used when traditional data mining and handling techniques cannot uncover the insights and meaning of the underlying data.

This type of data requires a different processing approach called big data, which uses massive parallelism on readily-available hardware.
