Many methods for mapping XML to relations have been proposed without considering the semantics of XML data before. But the semantics is very important to design schemas for storage, optimize queries, and check update anomalies, etc. In the presence of XML FDs which are specified over DTDs, this paper presents a method based on the hybrid inlining to map XML to relations for storage.
有许多文章提出了根据DTD将XML映射成关系的方法,但都没有考虑XML的语义,而语义信息对数据存储模式设计、查询优化、更新异常检查等来说是十分重要的,如果在DTD上指定了XML的函数依赖,在映射到关系数据库中就需要将其考虑进去。

Hybrid Inlining is a good approach from mapping DTD to relational schema, it inlines lots of nodes into table, it reduces the number of joining table when we query table, but Hybrid Inlining has some problems when data is deleted or inserted.
Hybrid Inlining方法是一种比较常用的映射方法,此方法将多个元素内联到一个表中,从而可以降低查询时连接操作的次数,但同时也存在一些诸如删除异常、插入异常的问题。
