Evolving information systems: meeting the ever-changing environment

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

Integrating architectural models

The diversity of architectural models in enterprise architecture is a problem for their integration. In this paper we distinguish three kinds of models from each other and their visualization, and we illustrate how the distinctions can be used for model integration within the architectural approach. Symbolic models express properties of architectures of systems, semantic models interpret the symbols of semantic models, and subjective models are purposely abstracted conceptions of a domain.
