Abstract
This paper describes the effect of schema evolution operations on the implementation of methods. The effect of these operations is captured as temporary inconsistencies. Extensions for handling these temporary inconsistencies in our Graphical Object-Oriented Schema Environment prototype, called GOOSE are described. In GOOSE, the schema information is maintained as a set of system objects of system defined classes. In order to maintain these temporary inconsistencies, the system classes have been augmented with two classes, namely Uses and Stubs, as specialization of the system class Class. Furthermore, schema evolution operations for explicitly resolving these inconsistencies are defined.
