Case-Based Reasoning for Information System Design

We present a process model that applies case–based reasoning techniques to information system design. Describing the process model we focus on similarity and case adaption aspects. We are currently implementing the process model in a research prototype called CBModeler. The CBModeler project shows how the development of information systems can be supported by reusing design specifications from former projects. It assumes that all designs are derived from a reference model that describes the most important aspects of a specific information system domain. Thus we are also integrating schema–based and model–based reasoning techniques. We introduce the notion of design and design component, similarity and adaption process. Furthermore, we describe how a meta–model can be used to preserve system wide consistency and a reference model to preserve consistency in a domain. Finally, we give a simple design scenario.
