基于倒排表与B+树的联合索引技术
Combined Index Techniques Based on Inverted Table and B+ Tree
摘要
Abstract
In order to improve the query effeiciency of hybrid extensive Makeup Language(XML) document, this paper proposes a combined index technology based on inverted table and B+ tree. The DTD structure index and content index uses inverted table as index units, and XML document index takes B+ tree as the basic organization of its index. Identification information is set in node coding of DTD structure index, and it can help to determine the document which needs to query. And XML document hybrid query is achieved by establishing DTD structure index, XML document query and content index. Theoretical analysis and experimental results show that the proposed technology not only has lower space overhead, but also has higher index efficiency.关键词
