Big data is large and complex data sets for which traditional data processing applications are inadequate. Challenges include analysis, capture, data curation, search, sharing, storage, transfer, visualization. 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. Big Data is defined as a collection of data sets, which are so complex and large that the data cannot be easily captured, stored, searched, shared, analyzed or visualized using available tools. In global markets, such "Big Data" mostly appears during attempts to identify business trends from available data sets. The processing of "Big Data" requires specialized software capable of coordinating parallel processing on thousands of servers simultaneously.
