摘要
提出了数据仓库即样本库的观点,给出了用于数据仓库的概念设计样本模型(SM)。SM以事件为中心,每类事件即是数据仓库的一个主题,通过对参与事件的实体及其上关系(层次、分类和组合)的描述定义事件的表示空间。
The view of data warehouse that is sample warehouse is presented and sample model (SM) for data warehouse conceptual design is invented. SM is an event-centered model, which is an equivalent of subject. By defining the entities that participate in event and the relations (hierarchy, classification, and assembly) among them, a representing space of the event set is defined.
