A graph-based model for describing Schemes and instances of object databases together with a graphical data manipulation language based on pattern matching are introduced. The data model allows the explicit modeling of classes and relations which contain objects and associations, respectively. GOAL consists mainly of two operations, the addition and the deletion. These perform on every part. of the instance where a certain pattern is found. We will present. the syntax and the semantics of the language, and show its computational Completeness.
