Abstract :
A formal framework for a generalized object-oriented database model (OODB) is presented, which can be used to model fuzzy and uncertain information. This model is built upon a generalized algebraic type system and a generalized constraint system, which are both used for the definition of so-called generalized object schemes and generalized database schemes. In this paper, both the data definition and the data manipulation aspects of the database model are introduced, together with the definition of an object algebra
