The numerous information systems design methods and specification techniques being proposed, can be compared on the basis of different criteria. In this paper a framework for ordering information systems modelling techniques based on meta models is proposed.

To meet the demands of organisations and their ever changing environment, information systems are required which are able to evolve to the same extent as organisations do. Such a system has to support changes of all time-and application-dependent aspects. In this paper, requirements and a conceptual framework for evolving information systems are presented.(More)
In this article, we discuss the need for information systems capable of evolving to the same extent as organisation systems do. A set of requirements for evolving information systems is presented, implying the importance of the time concept in these systems. On the basis of these requirements an architecture and a conceptual framework for evolving(More)
