object level to the relational level allows the use of structural information from the frame model, FRM, to objects. the utilisation of structural semantic information for to the multiprocessor relational database system, classes to COCOON algebra. Moreover, there are the mapping of the remaining operational compois benecial in reducing the semantic gap between query and update processing. The mapping from the and relations. The introduction of the object level the frame level and the relational level and enabling in INGRES Currently, we are working on [Rys 94]. operations over a COCOON database represented nents and on the mapping of frame class instances INGRES. We also have a mapping from frame query well-established, ecien t mechanisms for data storto the object model, COCOON and from COCOON age, data access, data sharing and recovery under failure.
At present, we have implemented mappings for some early results on the parallelisation of update [Mor 91]
