“大数据”是指以多元形式,自许多来源搜集而来的庞大数据组,往往具有实时性。在企业对企业销售的情况下,这些数据可能得自社交网络、电子商务网站、顾客来访纪录,还有许多其他来源。这些数据,并非公司顾客关系管理数据库的常态数据组。从技术上看,大数据与云计算的关系就像一枚硬币的正反面一样密不可分。大数据必然无法用单台的计算机进行处理,必须采用分布式计算架构。它的特色在于对海量数据的挖掘,但它必须依托云计算的 “Big Data ” refers to a large data set that is collected in many forms and from many sources and is often real-time. In the case of business-to-business sales, these data may come from social networks, e-commerce sites, customer visiting records, and many other sources. These data are not normal data sets of the company’s customer relationship management database. Technically, the relationship between big data and cloud computing is like the positive and negative of a coin. Big data must not be handled by a single computer and must be distributed computing architecture. It features a huge amount of data mining, but it must rely on cloud computing
