摘要
完善的数据库系统需要具备良好的备份恢复功能和恢复模块,这样才能在工作中完成自己的使命,因此,加强数据备份和数据恢复的研究具有重要的作用。从实践中看,和其他信息系统一样,HIS系统的的可靠性有待于巩固,特别是系统内一些不可预知的软硬件故障,影响系统的正常运行,乃至破坏相关数据,甚至造成系统瘫痪等。本文研究一种备份与恢复机制,以解决两类典型数据库故障,事务故障和系统故障。最大限度的利用医院现有的软件、硬件与网络平台,较好的考虑了医院的数据容量需求,满足了实际需要中的及时性与可靠性。
@@@@The perfect database system needs good functions and module of database backup and recovery,so as to work to complete their aims. Therefore,the research of data backup and data recovery is important. Like other information systems,the reliability in HIS needs to be consolidated,especially the failures in some unpredictable system of hardware and software,which will affect the normal operation of the system, and even destroy data, or even cause system paralysis. In this paper, studying a backup and recovery mechanism to resolve two typical database failures,transaction failure and system failure. Maximize the use of the hospital information software, hardware and network platform, to fulfill the needs of data capacity and satisfy the timeliness and reliability to solve the real problems.
