Integrating Models of Quality Management Methods by an Object-Oriented Repository P. Peters, P. Szczurko This paper deals with an integration approach of quality management methods using the deductive object-oriented DBMS ConceptBase as a repository. Based on the IRDS standard we defined a distributed modeling environment. The experiences we had during the modeling process in the research project WibQuS emphasize the need for object-oriented abstraction mechanisms and deductive reasoning. Furthermore the developed conceptual model is a framework not only for specification and evolution of method models but also for information browsing in a distributed information system.
