XML查询语言XQuery的研究与实现

Research and Implementation of XQuery

XQuery是一种对XML结构的文档和数据进行查询的语言。在对该查询语言规范体系分析、理解和研究的基础上,提出了支持W3C的XQuery语言的查询处理引擎的体系结构。针对各个输入输出和处理模块按数据流的方式逐一进行分析,对整个系统的运行状态做了一个总体的介绍。按照这个体系结构,一个XQuery查询处理引擎已经被实现。

XQuery is a descriptive language which can query any XML- structured data, physically store in medium or viewed as XML. Based on the research of XQuery,illustrate the structure of our implement query engine. Give out a whole description of the running state of the system according to the analysis of the different modules. An XQuery processing engine has been realized according to this architecture.
