XML数据的结构化处理方法

越来越多的数据采用XML格式表示和交换，对XML数据的有效访问方法是目前需要解决的关键问题之一．对通过面向对象数据库系统访问XML数据的方法进行了讨论，提出了将XML数据映射到对象模型的规则以及建立XML数据的OODB模式的方法．为了建立高效地访问路径提出了一种XML数据的结构索引，并介绍了利用结构索引实现基本的数据操作的方法．实验结果表明，提出的方法具有较高的效率。

A METHOD FOR STRUCTURIZATION OF XML DATA

In this paper, the authors discuss a method for accessing XML data through object oriented database system. They propose rules for mapping XML data to object model and a method to establish OODB schema for XML data. They also give a method to create a temporary DTD by extracting structure information from XML document on the need of schema building. In order to establish efficient access path, the authors put forward a structure index for XML data, and introduce a method of implementing operations based on structure index. Experiments with real life XML documents indicate that this method is effective.
