Abstract :
Fuzzy conceptual data modeling is concentrated on in this paper. Based on possibility theory, A conceptual data model IFO is extended. Different levels of fuzziness are introduced and the corresponding graphical representations are given. IFO data model is this extended to fuzzy IFO data model, denoted IF2O in the paper. Attention is paid to the fuzzification of objects and relationships, specially on that of ISA relationships
