Abstract

PBS (a general purpose Picture Building System) is presently supported by a relational database (XRM), through an interface called GXRAM. A new interface (GSYSR) has been developed on top of System R, in order to allow PBS to use ordered relations, not directly supported by System R.

The GSYSR interface is used to create or delete ordered relations and to manipulate them when explicit reference to the ordering is made. Otherwise the usual data language interface of System R can be used on both ordered and unordered relations.

This paper describes the main features of the interface and discusses some essential features of a relational database system to be used for supporting a PBS-like system.
