摘要: 分析了数据库管理系统中数据存储实现策略所采用的系统管理表空间(SMS)和DBMS管理表空间(DMS)这两种主要的表空间管理方式。基于PostgreSQL数据库管理系统,给出了在其上实现这两种表空间共存的策略,并描述了DMS表空间的实现方法。

Abstract: Tablespace is the main data storage management strategy of DBMS. This paper analyzes the two primary approaches to manage the tablespace: system managed space(SMS) and DBMS managed space(DMS). Then it proposes a strategy to co-exist the two strategies based on PostgreSQL, and especially presents the method for the implementation of DMS.
