<jats:p><jats:bold>Abstract. </jats:bold> To meet the demands of organizations and their ever‐changing environment, information systems are required which are able to evolve to the same extent as organizations do. Such a system has to support changes in all time‐and application‐dependent aspects. In this paper, requirements and a conceptual framework for evolving information systems are presented. This framework includes an architecture for such systems and a revision of the traditional notion of update. Based on this evolutionary notion of update (recording, correction and forgetting) a state transition‐oriented model on three levels of abstraction (event level, recording level, correction level) is introduced. Examples are provided to illustrate the conceptual framework for evolving information systems.</jats:p>
