摘要
针对异构数据集成过程中的模式转换问题,提出一种XML模式与关系库模式的转化方法,通过定义XML Schema与关系模式之间的转换规则,以XML Schema文档树生成的结点树为基础,实现了XML模式与关系模式的映射。该方法的最大特点是它不仅可以反映数据的结构特征,而且还能表示数据的语义约束。
An approach to set up the conversion between the XML schema and the relation schema in the progress of isomerous data inte-gration is presented in this dissertation.In this approach,the conversion rules between XML schema and relation schema are defined first.Based on the XML schema document tree,a node tree is created.Then the conversion is implemented according the node tree.It not only reflects the structure characteristic of the data,but also keeps most of the semantic attributes and constraints of the data.
