Multi-center cross-platform mass data exchange and sharing method and system

According to the multi-center cross-platform mass data exchange and sharing method and system, the corresponding target number can be determined according to the data exchange level of the data exchange request, the data exchange request is sent to the preferred node of the corresponding target number, the user terminal can only send the data exchange request once, and the user experience is improved. The data information is acquired from the plurality of data analysis nodes, and the corresponding data analysis node is selected according to the matching value, so that the data exchange efficiency is improved; meanwhile, data query times and time are reduced, and data exchange delay is reduced. 本发明提供了一种多中心跨平台的海量数据交换与共享方法及系统，可根据数据交换请求的数据交换等级确定对应的目标数量，向对应目标数量的优选节点发送数据交换请求，用户终端可以只发出一次数据交换请求，就从多个数据分析节点中获取数据信息，并且根据选配值选取对应的数据分析节点，提高了数据交换的效率；同时减少数据查询次数和时间，降低数据交换延迟。
