| Abstract: | The current status of Deductive Data Base System(DDBS) in modeling and approaches is discussed.Based on the integration of loose and tight coupling a mechanism of realizing DDBS is proposed.Then the deductive data base system is briefly introduced, and the design of multiquerylanguage and two-level knowledge representations are discussed as well. Finally,a graph-based recursive query processing algorithm is given. |
