摘要： 分析当前流行的XML-Schema设计方法。针对XML文档存在数据冗余的现象,改进了设计方法,提出基于E-R模型的实体加权算法。该方法使数据类型定义基准量化,进而在保证XML树结构的前提下最小化数据冗余。

关键词: E-R模型, XML模式, 数据冗余

Abstract: This article compares and analyzes the currently exiting approaches of designing XML-Schema, and presents an entity-weighted approach based on E-R model to improve those approaches. With this new approach, XML-Schema can make XML documents minimize data redundancy and maximize element connectivity.
