| 摘 要： | XML数据关系存储有很多优点,但必须将XML的树型结构映射为关系表的二维表结构,以基于结构的映射方法为基础,根据XML数据和查询的特点,结合纯XML查询的优点,提出使用混合映射来解决XML数据的存储问题,即文本和枚举仍保留为XML文档,其他部分映射为关系数据.

| Abstract: | Storing XML files with RDBMS has advantages over other technologies,but it implies that the tree structure of XML must be changed into tables.Considering the features of XML data and related query,a new way to store XML is given to take advantage of both RDBMS and native XML based on the Inlinings,that is,text and enumeration type element store are saved as XML document and others as RDBMS according to inlining technology. |
