In this paper we investigate the integration of application software systems into an Ada environment using the model given in the Stoneman requirements. We consider especially the aspect of making available the user functions of such systems to an APSE end user. We outline that within the Stoneman model this can only be achieved by integrating the application software system interfaces into the MAPSE level. We suppose that an application system can be described by an abstract data type: the package facility of Ada is used to realize such an abstract data type. The problems are discussed in detail by showing how to integrate an existing data base system.
