✦ Synopsis


In this paper, a fuzzy Object-Oriented Data model FOOD is defined based on the Ž extension of a Graph-based Object model D. Lucarella and A. Zanzi ''A graph-oriented data model,'' in Database and Expert Systems Applications, R. Wagner and H. Toma, . Eds., Springer-Verlag, Berlin, 1996, pp. 197᎐206 , in order to manage both crisp and imperfect information. † These capabilities are requisites of many current applications dealing with data of different nature and with complex interrelationships. The model is based on a visual paradigm which supports both the representation of the data semantics and the direct browsing of the information. In the extended model both the database scheme and instances are represented as directed labeled graphs in which the fuzzy and uncertain information has its own representation.
