| 摘 要： | 首先指出数据库系统间存在异构现象,这种异构现象主要体现在数据模型结构不同及数据模型模式不同两个方面,并针对两个不同方面讨论了异构数据库系统信息交互的两种可能解决方案,然后提出间接解决方案中需要中介且XML可以充当此中介,并在接下来讨论了基于XML异构数据库系统信息交互的解决方案,最后总结出此解决方案关健在于XML文档结构与数据库模式之间的双向映射。

| Abstract: | Firstly,The author refered that it existed isomerism between two database,and this isomerism main showed two difference aspects which including data model structure difference and data model mode difference,then aimed directly at the two aspects to argue the two possible solution of information exchange of isomeric database system ,and present that the mediate solution needed mediation and XML could act as this mediation,secondly, the author argued the solution of information exchange of isomeric database system over XML,Iastly it concluded that the key of the solution is the mapping between XML schema and database model. |
