摘要 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 。 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.
