摘要
数据共享是信息资源管理的核心内容。传统"点到点"数据共享方式存在如下缺陷:增加新的应用时就要建立该应用系统到已经存在的应用系统之间的连接,在不同的应用系统进行升级或接口发生变化时会遇到很多的麻烦,至少需要重新修改不同应用系统之间的连接,这导致其缺乏灵活性。本文针对上述缺陷提出了基于信息超市的数据共享方式。该方式使得新的信息资源能动态地加入并且不需要修改系统间的接口。
Data sharing is the core content of information resources management.The traditional point-to-point way of data sharing features the defects： to increase the time necessary to establish new applications in the application system to an already existing link between the applications,to meet many troubles in different application system upgrades or interface changes,to re-modify the connection between different applications at least,which do not lead to its flexibility.This paper presents a data sharing mode based on information supermarket.The mode makes the new information resources dynamically join without modifying the interfaces between systems.
