Abstract

GQL is a formal query language for graphically manipulating a semantic database. The language provides a set of pattern images and a set of simple rules for constructing pattern graphs. Users describe their queries by drawing 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 operations. Implementational issues of a GQL interpreter and its relation to other query languages are also discussed.
