HIS系统历史数据转储的设计与实现

Design and Realization of Historical Data Dump in HIS System

从数据库提供的功能入手,指出双机热备、导入导出登常规转储方法存在的缺陷,并提出利用数据分区和基于存储过程、触发器的数据转储方法。介绍两种方法各自的实现原理,详细描述了具体实现步骤,最后给出使用范围。

Starting with the database function, it points out defects in regular dump methods such as dual-computer hotstandby, introduction and deduction, etc., and puts forward to take use of data partitioning and data dump method based on storage process and trigger. Moreover, it introduces the realization principle of two methods respectively, describes the specific realization steps, and gives the usage range.
