Conference paper


GQL is a graphical formal query language for manipulating ’a database. By providing a set of pattern images, the language allows users to draw pattern graphs against the graphical schema of the database. This paper describes various aspects of GQL: the underlying model, the pattern images and graphs, and the representation of database operations.
