当今,我们正处在一个数据爆炸的时代。从斯诺登曝光的文件显示:美国国家安全局每天收集全球高达近50亿份手机通话纪录和20亿条手机短信息。沃尔玛每小时从顾客交易中获得数据为100万GB,印出来可装2 000万个文件柜。据IDC预计,到2020年全球数据总量将超40ZB,相当于地球上所有海滩上的沙粒数量的57倍。海量数据的产生、获取、挖掘及整合等技术的应用将带来新一轮信息化革命,将对企业组织、决策、管理、业
Today, we are in an era of data explosion. The document exposed by Snowden shows that the NSA collects as many as 5 billion copies of global mobile phone calls and 2 billion mobile messages daily.

According to IDC, global data will exceed 40ZB by 2020, equivalent to 57 times the amount of sand on all beaches on Earth. The application of such technologies as generation, acquisition, excavation and integration of massive data will bring about a new round of revolution in informationization and will exert great influence on enterprises’ organization, decision-making, management and industry
