| 摘 要： | This paper focuses on the issues of categorical database generalization and emphasizes the roles of supporting data model, integrated datamodel, spatial analysis and semantic analysis in database generalization. The framework contents of categorical database generalization transformation are defined. This paper presents an integrated spatial supporting data structure, a semantic supporting model and similarity model for the categorical database generalization. The concept of transformation unit is proposed in generalization.
