摘要 多维数据模型是数据仓库和联机分析处理研究中的一个重要问题,该文根据电力负荷数据集的特点,提出了一种新模型,解决不同维公用一个底层层次属性,把系统中不完全的低粒度数据集和完全的粗粒度数据集在逻辑上无缝地结合起来支持联机分析处理的问题,这是其他多维数据模型所没有解决的。 Multidimensional data modeling is an important problem in the field of data warehouse and OLAP.Based on the characteristics of the data set of electric load forecasting,the paper introduces a new model to solve the problems of different dimensions sharing a common bottom level of hierarchies and incorporating incomplete data set of fine granularity and complete data set of coarse granularity logically to support OLAP which had not been solved by other models.
