基于关系模式下XML大容量文档查询方法的研究和实验

The Research and Experimentation of XML Bulk Document Query Method Based on Relational Mode

XML数据的半结构化特征,设计了一种新型索引模块,给出一种新的倒排索引方法。构建了利用高频路径产生的索引机制,通过映射实现表和XML数据文档之间的转换,实现XML数据库事务处理和版本控制,最后通过基于XML的路径查找算法的实验,快速检索出文件中重要的连续路径。

In view of the XML data＇s half structurized characteristic, the paper designs a kind of new index module, gives a new reverse index method, constructs the index mechanism which uses the high frequency way. Through the mapping, it realizes the trans- formation between the table and the XML data documents, also the XML database business processing and the version control. Finally it reaches the important and continual route based on the XML way for the experiment of algorithm searching, and to quickly retrieve the document.
