摘要
可扩展标识语言(extensible markup Ianguage, XML)的数据模型包括概念模型、结构模型和概念模型到结构模型的映像。框架可用于建立XML概念模型,XML说明描述(XML declarative description,XDD)可用于构造XML结构模型。给出了框架模型到XDD模型的映射方法,使二者构成一个完整的XML数据模型,不仅可用于建立XML数据库体系,而且能够实现对XML文档的语义处理。
A method of XML structural model derived from frame XML data model has involved conceptual model, structural model and its mapping from conceptual model. The frame applies to construct XML conceptual model, and XDD applies to construct XML conceptual model. The mapping method from the frame model to XDD model is given. When a whole XML data model with two models above mentioned is constructed, not only it can applies to construct XML data base system, but also to realize semantic process for XML document.
