医院信息系统数据分布式存储方案设计

A Deployed Data-Storage Design for HIS

医院信息系统（HIS）的数据量随着时间的推移,不断累积,数据库体积增长。数据库体积增加到一定程度时,会带来一些严重的负面影响。数据库的运行效率会受其影响而降低;日常数据库的备份、运行管理难度增加。这种运行效率的降低及日常维护难度的增加随着时间的推移持续恶化。本文所述的方案能在一定程度上缓解前述问题,其主要思路是将数据进行分布式存储,单一数据库的增长控制一定的规模以内。

The datasize of HIS is increasing persistent.When the datasize reach a certain grade,it will cause some serious problems. While The Efficiency of the system reduces,to backup the database as well as to manage the database becomes more difficult.This change continues over time. This article Discusses the solution of this issue. An effective way is making distributed store to the data of HIS.
