数据库归档技术在HIS海量数据存储中的应用

摘要

对于海量数据的完整保存是在医院信息系统(Hospital Information System,HIS)中一个重要的工作内容，任何一个在运行过程中的HIS，在没有特殊的处理前提下，其数据间都存在着有限存储与无限增长的矛盾。因此，本文主要分析在我院HIS当中数据的存储现状，并积极找出数据量不断增加的原因，介绍当前数据归档技术原理、操作原则及优势，从而使其更好的应用在HIS海量数据的存储工作中。%The complete preservation of massive data in hospital information system (Hospital Information System, HIS) is an important content of the work.The contradiction between limited storage and unlimited increase exists among data of HIS in the running process before special process. Therefore, this paper mainly analyses the status of data stored in our hospital in HIS, and actively find out the reason of data increase, and introduces the principle and operation and advantages of data archiving, so as to make it be applied in the HIS data storage more efficiently.
