Abstract

A binary relational database model is used as the heart of a coexistent database system architecture. The semantic binary relational model (SBRM) of information allows for evolutionary changes in the data base by breaking large constructs into atomic named objects. A graph representation of the SBRM schemas is used as an effective data base interface. Such an interface allows interrogation of the database by employing a sequence of graphical movements based on the schema graphs displayed on the screen. This paper describes a data base interface language which is based on manipulating graphical images of objects in an SBRM graph
