Zusammenfassung

In this thesis we define a framework for the specification of dynamic behavior of software systems. This framework is motivated by the state as algebra approach and the model-oriented language Z. From the state as algebra approach we use the idea of modeling the environment and the state components as structures of an institution. However, in contrast to the state as algebra approach, states in our framework are modeled by structures from any suitable institution not only those having of algebras as their structures. From Z we use the idea that environment, state spaces and relations between state spaces are specified using the same logic and how more complex relations can be constructed from simpler ones by means of the schema calculus. However, we differ from Z in that our framework can be instantiated by different institutions, while the approach of Z can only work because of the particular logical system used by Z.
