Abstract

This paper describes a generalization of the relational database model using first order predicate calculus with temporal operators. The generalization is intended to be a model for an intelligent database—one which employs reasoning in retrieving its data—and to suggest a query language for the system. An incremental approach to intelligent databases is employed, wherein a standard database model is augmented with temporal attributes and then with deductive capabilities. This paper builds on the work of Navathe on temporal databases and on Allen's algebra of temporal relations. The goal is a logical reconstruction of the model which results when the two approaches are combined.
