The POSTGRES Data Model

Lawrence A. Rowe, Michael Stonebraker

Open publisher page 223 citations

Abstract

Abstract : This paper describes the data model for POSTGRES, a next-generation extensible database management system being developed at the University of California StR86. The data model is a relational model that has been extended with abstract data types, data of type procedure, and attribute and procedure inheritance. These mechanisms can be used to simulate a wide variety of semantic and object-oriented data modeling constructs including aggregation and generalization, complex objects with shared subobjects, and attributes that reference tuples in other relations.
