• Resumen

  • A formal framework for a generalised object-oriented database model is presented, which is able to cope with fuzzy and uncertain information. This model is obtained as a generalisation of a crisp object-oriented database model, which is consistent with the ODMG de facto standard and is built upon an algebraic type system and a constraint system. Generalised constraints have been used to enforce integrity rules and to specify the formal semantics of the database model.
