|Title:||Reference Object Model For Database Systems Based On Set Theory|
|Author:||Ruschel Regina C.|
Magalhaes Leo Pini
|Abstract:||This paper presents part of a formalism proposal using set theory for a reference object model, being developed as a doctoral research thesis at the College of Electrical Engineering (FEE) of the State University of Campinas (UNICAMP), Brazil. The reference object model proposed is compatible to the standard ODMG-93, however more generic. The formalism uses set theory concepts to define types, classes, encapsulation, subtyping, inclusion and overloading polymorphism, instances (object/values), object identity and types/classes extents (extensions). The set theory concepts used are domains, relations (domain mappings), domain-relation associations, set inclusion and functional inclusion. This paper will only present the formalism related to abstract concepts of an object model, e.g. types, classes, encapsulation, subtyping and polymorphism. The main contribution of this work is a step toward a mathematical foundation for standardization efforts of object models for Object Oriented Database Systems.|
