摘要
现有的XML到关系数据的映射算法没有充分考虑DTD中所蕴涵的语义,如果DTD中蕴含函数依赖,在映射到关系数据库时应考虑DTD中的函数依赖,基于Inlining算法,考虑DTD中蕴含的函数依赖,提出了一种既能保持XML文档的内容和结构,又能保持函数依赖的从XML到关系数据模型的映射方法。
In the process of mapping XML to relational schemas,semantics of XML data are often neglected currently.It is of much importance to consider the possi- ble existing functional dependencies in DTDs.Based on inlining method,a new method of mapping XML to rela- tions is presented,with the content and structure of XML and functional dependencies of DTD preserved.
