摘要
针对实现数据仓库系统的核心工作——数据建模,给出了一种基于需求分析、维度建模和物理建模的数据仓库数据建模方法。设计出标准化的建模规范,提出了总线结构的数据仓库总体建模实现方案,并给出了电力营销数据仓库数据建模的实例。
In allusion to realization of the core job of data bank system-the data modeling, this paper shows a method for modeling of data bank based on need analysis, dimensionality modeling and physic modeling, thus to design a standardized criterion for modeling. It gives an overall modeling realization scheme of data bank of bus structure and shows example of data modeling in building data bank of electric power marketing.
