摘    要:为提高数据仓库中多表连接的查询处理响应时间,本文结合数据仓库中多表连接的特点,利用面向对象中的消息机制,提出了一种基于ORV(对象关系视图)的并行多表连接查询算法,并对算法的磁盘I/O操作块数进行了分析,与单处理机及传统的多表连接算法进行了比较。

关 键 词:面向对象数据库  ORV  数据仓库  多表连接查询算法  数据查询

Abstract:To raise query response time of multi-table join in data warehouse, according to the features of multi-table join, the author proposes a parallel multi-table join query algorithm in this paper. This algorithm is based on ORV and the message mechanism of OO. Also the author analyzes the I/O cost of the algorithm and compares the algorithm with the single processor and the traditional multi-table join algorithm.
Keywords:Object_relational view Complex object Component object Parallel mechanism
