In this paper, the authors make a concerted effort for minimizing the computing cost by comparing and analyzing the different temporal data models of databases. This is a review paper. The paper begins with critical investigation of the constraints of relational model and then comparing the key concepts of various temporal data models. Finally, in the context of temporal perspective, the paper concludes with the analysis of these different models with a view to design an effective conceptual temporal database framework.
