基于索引的XML数据库的优化研究

Optimization of the XML Database Based on Index

本文基于Native XML数据库的特性，提出了一种自适应的优化索引方法，该方法能够根据XML数据文件的特点，结合ISP原理实现自动优化的KeyX索引。实验结果表明，它能有效地实时优化索引，保证XML数据库持续高效运行。

Based on the characteristics of Native XML Database, an adaptive optimal indexing methods, the method accord- ing to the characteristics of XML data files, combined with the the ISP principle of automatic optimization KeyX index. The experimental results show that it can effectively real-time optimization of the index, to ensure that the XML database conti- nued efficient operation.
