摘　　要：基于XML文档的逻辑结构主要通过DTD和XMLSchema两种方法实现 ,相对DTD ,XMLSchema具有更强大的描述能力 ,主要体现在一致性、扩展性、互换性和规范性上 ,有更强的应用前景 .本文具体就XMLSchema的优势和基于XMLSchema数据库向XML文档的转换进行了探讨 ,研究了利用数据库厂商直接提供的支持和找出关系数据库与XML文档之间的映射关系的解决方案 .最后给出一个应用实例 。Now the logic structure of XML text is realized primarily via two kinds of methods of DTD and XML schema. XML schema of XML mode is much more powerful in its ability of description in terms of its consistency, extension, conversion and standardization, hence having a more promising future. This article discussed the advantage of XML schema and the conversion between XML schema and XML text. One solution has been studied where database factory directly provides and finds out the mapping relation between the database and XML text file. Finally an example was given and a basic idea of the conversion of an object-oriented database to the XML text was described.
