信息通讯技术(又称ICT)的高速腾飞加快了数字化时代的到来,信息化、数字化已成为时下各行各业热议的话题。1983年,阿尔温·托夫勒在《第三次浪潮》中预言:“如果说IBM的主机拉开了信息化革命的大幕,那么大数据将是第三次浪潮的华彩乐章”。起初,大数据通常用来批量分析处理大量数据集和更新互联网搜索索引所需,但到后期并不只是用来表达数量概念。就目前来看,区别于传统数据,对大数据定义还未形成统一共识,但可以肯定的是,大数据时代 The rapid take-off of information and communication technology (also known as ICT) hastened the arrival of the digital age. Informationization and digitization have become the hot topics of all walks of life at present. In 1983, Arvind Toffler in the “Third Wave” predicted: “If IBM’s host opened the curtain of the information revolution, then the big data will be the third wave of the cadenza ”. At first, big data was typically used to batch analyze large data sets and update Internet search indexes, but later it was not just a concept of quantity. For now, different from the traditional data, the definition of big data has not yet formed a consensus, but it is certain that the era of big data
