XML模式到关系模式的转换研究

Research on the Transformation from the XML Schemata to the Relational Schemata

本文研究了XML模式,分析了已有的XML模式到关系模式的转换算法及其存在的问题,提出了新的转换算法XTR,并探讨了保留语义约束的方法。新算法更符合范式的要求,并且能处理多对多关系。

In this paper, the features of XML schemata are studied, and several algorithms and their problems on the transformation from the XML schemata to the relational schemata are analyzed. Then the algorithm XTR is presented, and the method to preserve semantic constraints is discussed. The results of the algorithm XTR are better than those of the algorithms analyzed according to the normal form, and the many-to-many relation can be translated in the algorithm XTR.
