摘要
针对传统远程教学系统的缺点的分析,将数据仓库引入到远程教学系统中,有利于对远程教学质量进行分析;能够科学的辅助教师了解学生的掌握情况,及时调整教学方法和进度。通过对主题域的分析和对粒度的划分,构建了远程教学质量分析系统数据仓库的多维数据模型,并对数据仓库的事实表、维表的设计进行了详细的研究。最后以SQL Server 2000平台为基础,给出了具体的实现。
Data Warehouse in network instruction system can benefit the analysis of the quality of network instruction;and can scientific help teachers knowing the students' grasp about knowledge scientifically and changing.This class by the analysis of disadvantage in traditional network instruction System.The data warehouse multidimension data model in network instruction system were introduced by the analysis of subject field and granularity,and detailed study in the fact table and demension table.As a foundation.take SQL Server 2000 platforms has given concrete realization.
