1、引言
随着先进的数据库技术和数据的普及应用,大量的数据积累的人类,以指数的比率正在迅速增长。进入九十年代,随着出现和互联网的发展,以及内联网和外联网,以及出现的虚拟专用网络及其应用系统,将整个世界变成了一个小地球村,人们可以超越时间和空间数据交换的在线信息和共同努力。通过这种方式,向大家展示在前面部不仅限于,各单位和行业一个巨大的数据库的信息,但广袤的海洋,人们在洪水滚动的数据。当数据量极度增长,如果没有有效的方式,由计算机和信息技术来提取有用的信息和知识,本来面对信息,如海洋,就像大海捞针一样亏损。据估计,大型企业数据库中的数据,只有7个应用一直很好。这样,相对于“数据过剩”和“信息爆炸” ,它也为“信息贫困”和“中的数据笼子” ,奈斯伯特惊呼“人类正被数据淹没,却饥渴于知识”。

With the sophisticated database technology and the popularity of data applications, the amount of data accumulated by mankind in order to index the rate is growing rapidly. Into the nineties, along with the emergence and development of the Internet, as well as the intranet and the extranet, as well as the emergence of virtual private networks and applications, will the whole world into a small global village, people can transcend time and space exchange of data on-line information and work together. In this way, to show people at the front of the department is not limited to, the units and the industry a huge database of information but the vast expanse of ocean, [资料来源:http://Doc163.com]
