,What’s in a relationship? On distinguishing property holding and object binding,ntrates on the modelling of relationships, with particular reference to CASE and methodology engineering. Existing models are examined and some problems are identified arising from the confusion of the connection aspect of relationships with their property-holding aspect. The separation of attribute

From information systems to knowledge systems, systems from a logical point of view, we show that the two most fundamental operations are inference (query answering) and update (‘data manipulation’). They have to be available in every system. Advanced information systems may allow for negative, disjunctive and uncertain information. Even more a

,Comments on “Theories of meaning and different perspectives on information systems” by P. Holm, K. Every semantic theory presupposes an ontology, or a theory about what exists. By uncovering the ontologies behind the various semantic theories used by people working on information systems, we can learn much about the limitations of their methods of analysis and specification.

,Comments on “A user-centered method for the development of data-intensive dialogue systems: An objeThe paper addresses an important issue: how to involve the users of a system into the development process of the system. Since different types of software systems impose different requirements on the system development process the paper confines itself to the development of one class of systems: data-intensive dialogue systems.
