【摘要】 研究了基于ＭＩＭＤ－ＣＬ模型的关系数据库并行查询系统的设计与实现技术，着重讨论了系统的总体构架、任务划分策略、数据划分策略、Ｂ￣＋树并行维护机制以及系统物理层数据的页面交换策略等关键问题，提出了可行的解决方案。在Ｍｕｌｔｉｔｒａｎｓｐｕｔｅｒ并行机上利用所述的方法实现了一个并行查询系统。更多还原

【Abstract】 The MIMD-CL model based design and implementation techniques of parallel query system in relationdatabase are studied in this paper.Particularly,the followings are discussed in detail:the framework of thesystem,task partition strategy,data division strategy,the mechanism of parallel maintainance on B+trees,and page exchange of data on physical level,then,the feasible solutions are presented.According to theidea presented above,we implement an experimental system on muItitransputer machine.更多还原
