Information in real world application is often vague or ambiguous. Currently, less research has been done in modeling fuzziness in conceptual data model and design of fuzzy databases. In this paper, based on fuzzy set and possibility theory, the fuzzy IFO model and the corresponding graphical representations are presented. In particular, we provide the approach to mapping a fuzzy IFO model to a fuzzy nested relational database schema.
