Abstract

Database management systems for non-standard applications, in particular for engineering applications (NDBS), constitute nowadays one of the most important challenges in the area of database research. Some of the major obstacles are concerned with problems of modelling and processing complex engineering objects. Some new kinds of overall system architectures have been proposed, and appropriate concepts for handling the new types of application objects have been developed in the last five years. Based on PRIMA, an NDBS-kernel prototype implementation, we motivate a workstation-oriented architecture for NDBS application systems. We explain a prototyped application system in the environment of VLSI-chip design, which serves as a practical example in handling complex objects. Analyzing the weaknesses of this initial approach, we derive general concepts for application linkage, discussing in particular key issues for an efficient object processing and language binding.
