摘　　要：以实现分布式查询的正确性、透明性及优化性为目标,针对粮食储备管理系统的分布式查询处理需求,系统地研究分布式查询处理器的总体设计、线程控制、消息通信、分布式查询优化等问题以及实现技术,弥补了SQL Server数据库中分布式查询功能的不足。Aiming at realizing the exactness, transparency and optimization of distributed query, this study mainly focuses on the need of distributed query processing in grain reserves management system combined with the distributed query technology. Moreover, it systematically explores the general design, thread control, information communication, distributed query optimization of distributed query processor and their implementation technique. This study has successfully solved the fragmentation transparency problem of distributed query in the present SQL Server database.
