Economic growth and industrial competiveness rely heavily on the use of data processing and automation, resulting in increasingly complex requirements being placed on computer systems of all sizes. The need to fulfill these requirements and the availability of new technology have led to a new product class: modular computer systems, each module realized on one board. These make the design of computer systems for individual applications possible. Fault tolerant multi-micro-processor systems, which can now be farreachingly projected, require for their design a quantitative and complete description. This can be achieved by considering the three models, queueing model, reliability net and diagnostic graph based on the set of hardware and software modules of the system. In this paper the parameters of the three models will be represented with aid of a relational data model, which serves as a basis for analytical and simulation procedures to obtain the characteristic indices of the system. T he performance characteristics in various reconfiguration states will be determined for the example of a special application of the fault tolerant real time computer system RDC with consideration of the relational data model.
