一种基于XML Schema的映射算法

A mapping algorithm based on XML Schema

论文基于XML Schema规范,提出了一种等价于XML Schema的数据模型是New_Schema,并实现了从New_Schema到关系模式的映射算法。实验证明,在XML文档的模式信息比较稳定的情况下,New_Schema映射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要优于文本、Xparent和DTD等方法。

According to the XML Schema specification,this paper presents a data model named New_Schema that is equivalent to XML Schema。At the same time,the mapping algorithm from New_Schema to relational Schema are completed in this paper。By experiment,it proves that New_Schema mapping method is better than other methods such as TEXT,Xparent and DTD on information maintaining during mapping,data querying and updating after mapping。
