DM3故障恢复技术研究

Research on the Recovery in DM3

故障恢复是DBMS的重要组成部分。提出了一种基于Redo日志、Undo日志和检查点的系统故障恢复技术 ,并详细介绍了它在数据库系统DM3中的设计和实现 ,最后还给出了相应的恢复算法。

Recovery is an important component of DBMS.This paper proposes a method of database recovery technique based on Redo log,Undo log and checkpoint.Moreover,we introduces its design and implementation in DM3 in detail.Finally,we write its recovery algorithm.
