摘要
从粒度分析的角度出发,对数据仓库、粒度、Delphi 7中提供的Decision Cube决策组件进行了介绍。然后举例说明了如何在数据仓库中按时间段综合数据的粒度以进行决策设计和分析的方法,并对库中的表进行数据决策和图表决策,以便从不同的角度来查看和概括库中的数据,完善整个系统的设计。并对使用Decision Cube这组组件需要注意的问题也进行了总结。
This paper introduces data Warehouse, Groin degree, Decision Cube. components in Delphi 7 from the angle of the analysising the grain degree. Then it illustrates with example how to do decision design and analysising in terms of time in Data Warehouse. And it carries on data decision and chart decision to the table which is in the database.The method provides convenience not only to view and generalize the data,but also to perfect the design of the whole system. What＇ s more, it gives a summary to the problem which should be. noticed in using Decision Cube components.
