摘要
本文根据 W3C最新提出的 XML Schema规范,提出了一种等价于 XML Schema的数据模型S-Schema,并实现了S-Schema到关系模式的生成算法和XML文档到关系数据库的加载算法。实验证明,S-Schema方法在数据转储过程中的信息保持、映射后的查询更新操作等方面的综合性能要优于文本、Xparent方法。
According to the XML Schema specification published recently by W3C, this paper presents a data model named S_Schema that is equivalent to XML Schema. At the same time, the mapping algorithm from S_Schema to relational Schema and the loading algorithm from XML document to relational database are completed in this paper. By experiment, it proves that S_Schema mapping is better than other methods such as TEXT and Xparent on information maintaining and data querying and updating.
