XML data is stored in a native tree format, separate from the relational data.
XML数据按照原生的树格式与关系数据分开存储。
Manipulations like this (backed by the proper relational theory) are at the heart of database query optimizers. The resulting tree is shown in Figure 2.
此类操作(由恰当的关系理论作为支持)是数据库查询优化器的核心所在。
However, due to the mismatch between the XML's tree structure and flat relational tables, mapping XML document to relational database is an involved problem. So it becomes a pop research direction.
然而由于复杂的树形XML文档和简单平坦的关系型数据库表结构之间固有的不匹配，使得XML到关系型数据库的映射实现十分困难，因此成为当前的一个热门研究课题。
