Description: In this paper we describe the GRAphical Database Interface (GRADI) of a Multimedia      Database Management System. As generally true, the user interface is an important part of a      system which strongly determines the effectiveness of using it. In order to find a natural way of      interacting with the MDBMS system we examined the query specification process used by      humans. We found that incremental query specification, natural ways of expressing joins and      an additional 'all'-operator are important to improve the query specification process making it      considerably easier to use in comparison with query languages like SQL. The Graphical      Database Interface described in this paper incorporates the mentioned capabilities as part of      the MDBMS system. We think that the principles are of general use not only for multimedia      systems but for any database query interface.
