| 摘 要： | 分析了多个异构数据库间数据共享的连接访问技术,指出了目前访问异构数据库系统所存在的问题,并提出了一种解决方案:在2个或多个异构数据库管理系统前端增加接口模块,数据交换双方经过约定,各自开发己方数据接口,首先信息发起方将自身访问信息形成统一格式的XML信息,然后将该信息发送给接收方。接收方将相应XML信息解析,形成自身格式信息后访问数据库得到所需信息,再将其形成XML信息回发给发起方,发起方再做相应的数据处理。这种方式可以是单向的,也可以是双向的。在整个数据交换的过程中双方不需知道对方具体的数据格式。这种方法解决了异构数据带来的一系列数据共享问题。

| Abstract: | This paper analyzes the technology of heterogeneous databases connection and data exchang and the current problems of heterogeneous database system.The author proposed interface module in front-end database management system network. The two sides exchanged data to develop their own data interface after agreement.First,the information sponsors will form a unified xml format, then that information is sent to the receiving side. After forming their own format information, the receiving side obtains the information they need in the database, then forms xml format information and back to the sponsors, then the sponsors do data processing.The program can be one-way and can be a two-way too. Both sides understand each other's interface, and do not need to know each other's data format. This approach helps resolve the problems of Heterogeneous data sharing. |
