学生成绩分析数据仓库的模型设计及实现

Model Designing and Implementation of Data Warehouse Based on the Analysis of Students' Score

随着信息技术的发展 ,许多高校建立了相对完善的管理信息系统。但是 ,现有的系统信息只能完成简单的查询操作 ,而不能获取潜在有用信息。数据仓库及其相关技术为解决此问题而产生。这里提出了构建学生成绩分析数据仓库概念模型、逻辑模型、物理模型的模型设计方案 ,并通过决策支持对象编程实现数据仓库的构建。

With the development of the information technology, many universities have established the management information systems that is relatively perfect, but the recent information systems can only accomplish the simple operations of querying but not obtain the potential and useful information. Data warehouse and correlated technologies are emerged to solve this problem. This paper puts forward the model designing methods for concept model, logic model and physics model to build data warehouse of the analysis of students' score and implements the building of data warehouse by the programming of decision support object.
