KRISYS - a KBMS Supporting the Development and Processing of Advanced Engineering Applications

In order to support non-standard database applications and, in particular, advanced engineering applications, enhanced DBMSs have to supply not only semantically enriched data and knowledge modeling concepts, but also means for constructing an application model in a stepwise, incremental way. The Knowledge Base Management System KRISYS, which is presented in this paper, has been developed along these lines. We give an overview of the system architecture and the individual components, illustrate the application design methodology supported by the system, and demonstrate the applicability of KRISYS in an advanced CAD framework. Additionally, we emphasize the need of refined concepts for efficient application processing in workstation/server architectures and sketch a processing model for such an environment.
