基于HIS的数据仓库建设与OLAP应用

Data warehouse construction and OLAP applying based on HIS

本文针对医院信息管理系统（HIS）对辅助决策支持不足，提出以HIS为基础建设面向主题的数据仓库，建立基于联机分析处理（OLAP）的医院决策支持系统。该系统采用数据仓库总线架构，通过共享一致维度集成各个相对独立的数据集市。在客户端针对不同的用户环境分别使用数据透视表服务和基于ADOMD的Web系统，极大地提高了系统的灵活性。

The paper introduces OLAP into the Decision Supporting System in Hospital Information System （HIS）. It solves the problem that the lack of Decision Supporting in traditional HIS. Adopting Data Bus architecture, the system constructs data warehouse by integrating several independent Data Marts through consistent dimensions. At client end, the application for query and analysis apply MDX language and Pivot Table Service respectively. The two methods provide facility for OLAP analysis.
