T_Chimera: A Temporal Object-Oriented Data Model

Abstract

Temporal data models are an active research area. However, although many temporal extensions have been proposed for the relational data model, there is no comparable amount of work in the context of object-oriented data models. This paper presents T―Chimera, a temporal extension of the Chimera object-oriented data model. The main contribution of this work is to define a formal temporal object-oriented data model and to address on a formal basis several issues deriving from the introduction of time in a semantically rich model like the object-oriented one. © 1997 John Wiley & Sons, Inc.
