Fuzzy conceptual data modeling is concentrated in this paper. Based on dealing with imprecise and uncertainty super class-subclass relationships, a conceptual data model ER is enhanced. Different levels of fuzziness are introduced and the corresponding super class-subclass relationships representations are given. ER data model is thus enhanced to fuzzy ER data model denoted EER. Where that could store, retrieve, and manipulate the imprecise and uncertain complex data is stored in the form of objects with fuzzy techniques applied on it to encapsulate the impreciseness and uncertainty.
