统一资源管理系统中查询模块的设计与实现

Design and Realization for Query Groupware of Universal Resources Management System

针对URMS的特点,在其查询组件中设计了一种基于流的XML查询算法。详细地介绍了由查询表达式构造查询自动机的步骤;实现了一个基于流的XML文档查询系统的原型。通过实验表明,提出的方法能够适应XML流的查询,在内存利用率上优于传统的基于内存的XML查询算法。

Responding to the trait of URMS, we design a XML stream querying algorithm in query groupware. We present a method of building query automaton and an implementation of XML stream query system. Experimental results show that the program supports the complex XML stream and outperforms the traditional memory - based algorithm in efficiency of memory.
