Big data is a large set of data collected from many sources in multiple forms, often in real time. In the case of business-to-business sales, this data may come from social networks, e-commerce sites, customer visit records, and many other sources. These are not the usual data sets for a company's customer relationship management database. Technically, Big Data and Cloud Computing are as inextricably linked as heads and tails of a coin. Inevitably, big data cannot be processed by a single computer; it must be processed using a distributed computing architecture. It is characterized by the mining of massive amounts of data, but it must rely on the distributed processing, distributed databases, cloud storage, and/or virtualization technologies of cloud computing. The meaning of big data is accompanied by the increasing popularity of human online behavior, collected by relevant departments and enterprises, containing the real intentions and preferences of data producers, non-traditional structure and meaning of the data .
