基于扩充E/R图的XML模式设计

Design XML Schema According to the Extended E/R Map

为了适应Web环境下的数据交换标准XML,实现软件工程中系统分析与设计阶段XML模式设计的规范化,研究了根据扩充的实体/联系图(E/R图)设计XML模式的规范,以XML模式树作为XML模式的数据模型,以扩充的实体/联系图(E/R图)作为现实的语义模型,建立了在E/R图基础上的XML模式设计,探讨了E/R图中的实体、属性、联系转化为XML模式树及其组成部分的转换规则.

To normalize XML schema design in system analyzing and designing stage of software engineering according to the data exchange standard on the Web, the normalization of XML schema design based on the extended entity/relationship map （E/R map） is studied. Regarding the XML schema tree as data schema and the extended E/R map semantic schema, the translation rules from the extended E/R map to XML schema tree are proposed.
