COCOON and KRISYS - a comparison

The design of Object Based Systems, which map object-oriented, semantic or knowledge representation models to an underlying database kernel system, in order to close the gap between application and database system, are currently considered as candidates for future database architectures. KRISYS (University of Kaiserslautern) and COCOON (ETH Zurich), as two prototype systems following this kernel architecture approach, will be compared in this report. We give a very short overview of the underlying models and query languages as well as their mapping approaches and their processing models, compare the corresponding features and discuss differences in both systems.
