We have seen many of these cases where companies are willing to share their achievements in the use of large data. In any paradigm shift in the IT Industry (Paradigmshift), a specific theme attracts a lot of attention from news media, investors and innovators, a shift that requires strong commercial price support. 　　This typical case is: customer service, distributed computing, and service-oriented architecture and language, such as JAVA. We have also seen a beneficial ecosystem of emergence, rapid praise or expansion capabilities of the core support technology in large data ...
