【摘要】 XML在关系数据库中的存储问题是XML研究领域中的一个重要问题。在总结多种映射方法的基础上,提出了一种方法将多个相似的XML文档进行解析,根据映射关系,生成各自的关系模式,并分析归纳出一个集成的关系模式,然后创建一个关系数据库,并在映射关系的基础上提取并存储XML文档数据到关系数据库。此方法以较为简洁的结构保存了XML文档的数据信息,其最大的特点就是不用考虑文档的模式信息(DTD,XML Schema)。并通过一个具体的实验结果来说明这种方法的有效性。更多还原

【Abstract】 Storing XML data in relational database is an important problem in XML field.On the basis of several mapping ways,a method to extract XML data to relational database is proposed.Firstly,similar XML documents and produces their relational schemas is parsed according to the mapping relation,then these relational schemas are analyzed,an integration schema is produced and a relational database is created.Finally XML data is extracted and stored to relational database based on the mapping relationship.The method uses some relative simple data structure to conserver XML data information.The prime advantage of this method is independent of DTDs or XML schemas,and any similar XML documents is parsed and stored in the same database.A concrete experiment result show this method is effective.更多还原
