网站群间数据交换与共享系统

随着我国电子政务建设的快速发展，政府逐渐拥有越来越多的应用数据，但是这些数据由各种相互孤立的系统所采集生成并管理，其服务的范围被局限在某个特定应用或某部门内部，各个数据库之间存在相当数量的数据重叠，大量数据的重复采集的同时也造成了大量的数据不一致的问题。提出一个网站群间数据交换与共享系统。采用一种基于SOA和JSON数据格式的解决方案来处理多网站间新闻共享与交换。各网站和交换中心均发布服务接收新闻，同时各个站点均向交换中心发布新闻，交换中心根据配置信息转发新闻到相关站点的对应栏目下。设计交换中心与站点前置机，通过简单的配置实现交换中心与各个站点间新闻转发，实现新闻交换。如果有新加入的站点也不需要额外处理，只需要配置新的栏目对应关系即可实现新闻的共享与交换。

Proposes a data exchange and sharing system between websites. Adopts a solution based on SOA and JSON data format handling multi-website news sharing and exchange.
