Conceptual design of fuzzy object-oriented databases using extended entity-relationship model. (English) Zbl 0979.68040
Summary: Entity-relationship – extended entity-relationship models play a crucial role in the conceptual design of relational databases as well as object-oriented databases. Recently, several approaches have been proposed to enhance object-oriented databases using fuzzy set theory. We introduce a fuzzy extended entity-relationship model to cope with imperfect as well as complex objects in the real world at a conceptual level. In particular, we provide the formal approach to mapping a fuzzy extended entity-relationship model to a fuzzy object-oriented database schema.
