Abstract

KRISYS is a prototype of a Knowledge Base Management System whose first implementation was completed at the University of Kaiserslautern in 1989. Since then, the system has been used for the development of various applications which allowed us to perform a well-founded evaluation of the system. In this paper, we summarize our evaluation by describing the major lessons we have learned from the design and implementation of KRISYS and, above all, from its use in the development of these applications. We address issues related with the concepts available for application modeling and processing, the support of designing an application, as well as the overall means for efficient processing in a workstation/server environment. Additionally, we point out in how far these experiences validate our approach or stimulate improvements and future research.
