摘要：Fuzzy conceptual data modelling 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 representatio ns 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. In this paper, the attention is pain on the fuzzification of attributes, and objects, especially on that of super class-subclass relationships
