基于对象关系模式的XML转换

Transformation of XML based on Schema for Object-Relation

本文讨论关系模式集合上的包含依赖与组合依赖,提出了基于对象类之间的继承和组合关系的XML文档的一般转换思路,这种转换方法可以减少转换过程中嵌套结构的随意性和具体问题的依赖性,同时由于通过XML文档本身保存了关系文件的语义信息,有利于问题的逆转换。

This paper describes the inclusion dependency and composition dependence based on the set of relational schemas,and proposes a universal methodology of the translation of XML based on the inheritance and composition. By this means,we weaken the random in nesting and the dependence for practical issues. Maintain the information of the original relations, the process also helps solve the anti-transformation for this issue.
