On the Representation of Temporal Object Roles in Object Oriented Databases

This paper outlines a generic core tem poral object model that provides support for the modeling of temporal object roles This model draws from notions introduced in some of our previous works on tempo ral object modeling by providing a speci c database model that provides a concep tual modeling context for temporal object roles The model achieves an integration of the ab stract concepts that characterize temporal objects The main purpose of the model is to provide a basic framework for temporal object informationmodels and information systems The model is based on a small number of simple temporal constructs and primitive temporal operations The simple set of modeling constructs of this model are temporal objects and temporal mappings A set of primitive operations is de ned on temporal objects that allows uniform viewing de nition insertion and manipulation of objects in temporal object databases A simple set of temporal con straints is also provided
