FUZZY OBJECT-ORIENTED DATABASE MODELING COUPLED WITH FUZZY-LOGIC

This paper presents a modeling approach which couples fuzzy object-ori ented database modeling with fuzzy logic. The modeling approach introd uced here handles fuzziness at attribute, object/class and class/super class levels in addition to fuzziness in class/class relationships and various associations among classes. We utilize logical rules to defin e some of the crisp/fuzzy relationships and associations which cannot be presented easily with object-oriented modeling features alone in th e class hierarchies. We think that incorporation of object-oriented da tabase modeling with logic along with usage of fuzzy set theory simpli fies the design of complex and knowledge-intensive applications and ha ndles uncertainty effectively, therefore resulting in a powerful model ing framework.
