内容：以SQL Server为系统平台，设计、建立数据库，并以此为基础创建数据仓库。

要求：利用实验室和指导教师提供的实验软件，认真完成规定的实验项目，真实地记录实验中遇到的各种问题和解决的方法与过程，并绘出模拟实验案例的数据仓库模型。

实验完成后，应根据实验情况写出实验报告。

二、实验原理及基本技术路线图（方框原理图或程序流程图）数据仓库，由数据仓库之父W.H.Inmon于1990年提出，主要功能仍是将组织透过资讯系统之联机交易处理(OLTP)经年累月所累积的大量资料，透过数据仓库理论所特有的资料储存架构，作一有系统的分析整理，以利各种分析方法如线上分析处理(OLAP)、数据挖掘(Data Mining)之进行，并进而支持如决策支持系统(DSS)、主管资讯系统(EIS)之创建，帮助决策者能快速有效的自大量资料中，分析出有价值的资讯，以利决策拟定及快速回应外在环境变动，帮助建构商业智能(BI)。
