英文摘要：

According to the characteristics of the era of Big Data and the changes it brings,it is clear that core of Big Data era is from data to decision making. The rise of real-time decision-making in the era of Big Data, from large enterprises to individual, is comprehensively analyzed and described in the paper. In the aspect of data-aided decision making, this paper discusses the effective methods of using statistic methods to support decision-making, deriving mathematical formula from data and acquiring knowledge from data. The combination of big data and cloud computing will achieve the mutual promotion and common development. Finally,this paper puts forward that big data not only support large enterprises and government making decision, but also support the personal decisions.
