Design and Realization of Logistic System Based on Data Warehouse

数据仓库是近几年出现的信息处理领域面向分析和决策的新技术。首先介绍了数据仓库的一般特征和体系结构,并通过后勤数据仓库原型为实例,详细介绍了数据仓库的设计与实现过程,最后提出了数据仓库环境下基于知识的智能查询方法———"5W+H"。

Data warehouse is an analysis-oriented and decision-oriented new technology in information processing.The basic character and the system framework of data warehouse are introduced first in this article.Passed on a prototype of the logistical data warehouse,the design and realization of data warehouse are expounded in detail,and finally an intelligent query method:'5W+H',which is knowledge-based in data warehouse,is put forward.
