A generalised object-oriented database model with generalised constraints
Guy De Tré, Rogier Caluwé · 2003
This paper presents a new formal framework for a generalised object-oriented database model that is able to cope with fuzzy and uncertain information. The generalised model is obtained as a generalisation of a crisp object-oriented database model that is compliant with the ODMG de facto standard and is built upon an algebraic type system and a constraint system.
