Performance Analysis of Distributed Data Base Systems

In this paper we briefly present the design of a distributed relational data base system. Then, we discuss experimental observations of the performance of that system executing both short and long commands. Conclusions are also drawn concerning metrics that distributed query processing heuristics should attempt to minimize. Lastly, we comment on architectures which appear viable for distributed data base applications. * Research Sponsored by the National Science Foundation under Grant MCS-8211528 and by the Defense Advanced Research Projects Agency under Contract N00039-C-0235.
