PBASE体系结构与并行性

THE ARCHITECTURE OF PBASE AND PARALLELISM

并行数据库系统以高事务吞吐量和低响应时间为目标，一个好的体系结构方案将大大有助于实现该目标．本文介绍并行数据库ＰＢＡＳＥ系统的总体结构、分派进程结构以及ＰＢＡＳＥ如何实现事务间与查询间的并行性．ＰＢＡＳＥ采用的体系结构可以方便地实现并行性，达到并行数据库的预期目标．

High transaction throughput and low response time are two important objects of parallel database, and a well-designed architecture will do good to it. This paper discusses the general architecture of a parallel database system-PBASE, the dispatcher process in it,and how to realize the parallelism of inter-transaction and inter-query. The architecture of PBASE can reach the objects of PDB efficiently.
