Abstract: Based on importing the concept of database space, this paper analyzes the characteristic of detail database dimension of data warehouse, abstracts to three logical dimensions from its statistic space: universal dimension, object dimension and main dimension, introduces a suit of modeling theory and method for constructing fact table of data warehouse, creates all potential fact table. This modeling process can be assisted by computer.
