摘要
本文介绍了一个由我们研制的树型关系数据库机TDM的并行操作算法.TDM具有通过共享存储器而紧密耦合的多机结构.在该系统中,数据库经划分后被分布存放于系统的多个磁盘上.据此,TDM可以在多个层次上并行地执行各种数据库操作.通过对这些操作的分析可以看出,TDM是一个性能良好的系统.
This paper introduces a set of algorithms of parallel operations of a database machine TDM,which is a tree-structured relational database machine implemented by us. The architecture of the TDM is a multiprocessor organization in which the processors are tightly coupled by sharing memories. Data of database are partitioned and then distributed in multiple disks of the system. The TDM can perform parallelly various data base operations in multi-levels. Analysis of these operations shows that the performance of the TDM system ??better.
