| 摘 要： | 对于基于DTD在关系数据库中存储XML文档,此处利用结点模型映射方法,实现用关系模式来表示目标XML文档的逻辑结构(即 XML模式或DTD).还介绍了如何在已建立好的关系模式中添加约束用来保持原有XML文档中隐含的约束信息,此外XML文档的元素之间通常是相互递归的,这里也对XML文档中在出现递归的情况时,如何来存储递归的XML文档进行说明.最后通过举例,证明此种方法是合理有效的.

| Abstract: | Among the methods of storing XML documents in relational database based on DTD,the relational model is used to express the logical structure of the object XML document(XML model or DTD) by using the Node-Model mapping method.How to append restrictions in the relational model that has established for holding the restriction information in original XML document is introduced.Furthermore,there always have recursions among the elements,thus,how to storing recursive XML documents under the circumstance is also i... |
