In this paper, we describe a hedge algebras based approach to modelling uncertainty infuzzy object-oriented databases. Membership value reflects the degree of fuzziness existing in the datavalues and uncertainty is extended to the class definition level and is the basis for the determinationof the membership of an object in a class. On this basis, we recommend methods of determiningthe membership degree on characteristics of fuzzy attributes, object/class. class/superclass, and inaddition, multiple inheritance was discussed and analyzed.
