Abstract

Abstract: On the base of researching the proposed XQuery Engine and the optimization of XQuery，in order to reduce compilation time and runtime，a new synthetical optimization method based on the XQuery query instance itself is proposed.

Key words: Enterprise Information Integration（EII）, XQuery engine, query optimization, query rewriting

摘要： 通过分析研究已有的XQuery引擎和XQuery查询优化的方法，从减少编译时间和执行时间角度出发，提出了一种基于XQuery语句自身优化的新型综合性优化方法，经过XQuery中某常见查询进行仿真实验，可以说明该新型综合优化方法有较强的优势，可以大大地提高XQuery引擎的查询效率。
