The advent of large data enabled business intelligence to truly enter the 21st century. But in fact, the word "big data" is not a solution, but a kind of problem. What values are hidden in these petabytes of data, and what we can get out of it, and to guide all aspects of business deployment. But this huge amount of data is actually not very useful. 　　Therefore, in order to use its hidden value, enterprises need to collect, filter, and through the emotional analysis of the application, positioning tools and other technologies to analyze it to generate useful information, so as to serve the future business development. Clouds can be used as ...

Experimental analysis on computing performance of massive data based on GemFire Xu Xiang, Shiming, Lio, Zhu Yu in this paper, a distributed Memory database experiment platform based on GemFire is proposed for the real-time and dynamic scalability processing of high performance computation of multi-source dynamic mass data in traffic field. Using the key-value data storage structure and the distributed dynamic member relationship, the computational performance of the floating vehicle system is tested and analyzed by loading the real data of the float car in the whole cloud computing architecture. The experimental results show that the platform can shorten the computation time of tens above large data to 10 of the original system.

Recently, the Municipal People's Congress representative Tibao wrote a written opinion and will be held next week in Shanghai "two sessions" on the submission.　　In his written comments, he analyzed the most direct reason of "Shang and Zhu Upside down", and proposed "the transfer of commercial building reference ordinary residential tax" to reduce the cost of office transfer. On one side is the housing market "high fever", while the vacancy rate of office buildings and shops remain stubbornly persistent--the property market is trapped in the imbalance of "Shang hang upside down".　　The dominant result of the abnormal development is that more and more enterprises, especially the private enterprises can not afford to buy office room. Tibao analysis, "Shang Hang upside down" shows that the housing bubble has ...
