摘要
数据仓库改变了传统的以支持查询为主的事务型处理,变成以面向主题为主的分析型处理,并在此基础上建立了联机分析处理和数据挖掘应用,以适应快速的访问和支持决策分析等操作。本文使用了信息动态打包法构造概念模型和逻辑模型,并通过事实星座模式构造物理数据存储模型,来实现英语教学信息数据仓库的构建。
Data warehouse changes the traditional routine treatment based on support inquire. It becomes the analytical treatment based on theme. And in this way, the on-line analytical processing and data mining applications are established to adapt to the rapid visit and the support of decision-making operation. The article uses the information dynamic package method tectonic concept and logic model to achieve an intelligence data warehouse by which the fact constellation model constructs the physical data storage model.
