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.
