Abstract:
Based on RDB, this paper introduces the hierarchic primary key model (HPKM) based on E-R model and its strongpoints, presents the approach of the transformation from E-R model to HPKM, discusses the dimensional hiberarchy of HPKM. It analyzes the method of the transformation from HPKM to multidimensional model.
