异构XML文档类型定义的转换与集成

XML 数据的集成是当前的研究热点之一 .由于不同设计者的自治性 ,描述同一领域内容的 XML 文档可能在语义和结构上存在异构性 .提出一种异构 DTD的转换和集成方法 ,将 DTD转化为 IDMX模型的表示 ,然后通过模式比较、模式变换、模式合并与冲突消解的过程得到全局模式以及全局模式到局部模式的映射 .并介绍了异构 XML 数据源集成系统 KD- XIS

Transformation and Integration of Heterogeneous XML DTDs

The integration of heterogeneous XML data sources is a hot research top ic. Due to the autonomy of different XML designers, XML files may be heteroge neo us both in structures and semantics. This paper presented an approach to transfo rm and integrate heterogeneous DTDs. DTDs were converted into a data model called I DMX. Then schema comparison, schema transformation, schema unification and confl ict resolution were performed to get a global schema according to which queries c an be submitted. Finally a system called KD-XIS, which is designed for integrat ion of heterogeneous xml data, is introduced.
