数据是什么?数据有什么用?打开网页,你是否会发现,当你在网上商城购买婴儿奶粉后,下一次登录,商城便会自动将许多母婴产品推荐给你。你可知道,科学家可以通过对网络搜索的热词进行统计,然后得出某一区域将要爆发流行疾病的预测。从各种各样类型的数据中快速获取有价值信息的能力,就是当下最流行的大数据技术。早在1980年,著名未来学家阿尔文·托夫勒便在《第三次浪潮》一书中,将大数据热情地赞颂为“第三次浪潮的华彩乐章”。 What is the data? What is the use of the data? Open the web, you will find that when you buy baby milk powder in the online store, the next login, the mall will automatically recommend many of your maternal and child products to you. You know, scientists can make predictions about the epidemic of an outbreak in a region by counting terms that are web-searched. The ability to quickly access valuable information from a wide variety of data types is the most popular big data technology of the moment. As early as 1980, the famous futurist Alvin Toffler enthusiastically celebrated big data in the book The Third Wave as “the colorful wave of the third wave.”
