【摘要】 本文介绍了一个由多机硬件支持的关系数据库管理系统 TDM 的设计与实现.TDM 系统采用了树结构的紧密耦合式多处理机硬件、分布存放数据策略、并行的关系操作算法,多查询优化及多机任务调度策略等措施,使系统获得了较高效率.TDM 系统同时还设置了较为完备的数据库管理功能.更多还原

【Abstract】 This paper introduces a relational database management system supported bymultiprocessor,TDM.In the TDM,in order to achieve high efficiency,we adoptsome measures including the tree-structured dose-coupled multiprocessor hard-ware,the stretagy of data distribution,the parallel processing manner of relationaloperations,the multi-query optimization,the stretagy of task schedulling inmultiprocessor and so on.At the same time,we also implement the completed func-tions of database management for the TDM system.更多还原
