A fuzzy object oriented data model

Abstract

The increasing complexity of real applications in the field of multimedia information systems requires the enhancement of modelling capabilities of object oriented data models (OODMs) in order to deal with imprecise and uncertain data. Some fuzzy extensions of the OODMs have been proposed in the literature, in which imprecision and uncertainty are managed at the level of object attributes and relations. What is still lacking is a unifying and systematic formalization of these extensions. In this contribution, starting from an existing graph-based-object model, the authors propose a fuzzy object oriented data (FOOD) model for the management of imprecise data.<>
