摘要
数据仓库是数据管理信息领域的一种新技术 ,主要用于提高数据查询效率及支持决策 .本文将数据仓库技术引入数据库系统中 ,采用数据仓库的方式组织数据库 ,来克服在数据量大和网络应用中数据库系统效率不高、数据难以转化为有用的信息及不满足长期分析预测的需要等缺点 ,并结合锦天化公司生产管理的实际 ,提出引入数据仓库技术的数据库应用系统的具体设计方案 .
Data warehouse is a new technology in data management and information, and is mainly used to raise efficiency of data querying and to support decision. We use the theory of data warehouse to design database application system and to organize the database system in order to overcome the shortcomings of the database application system, such as low efficiency when there is a large number of data or in a network, the data is difficult to transfer into useful information, and it can't satisfy the needs of long time analysis and prediction. According to the actual situation in the Jinxi Nature Gas Chemical Co. Ltd. , a concrete design of such a system is put forward in the paper.
