“…Considering the operating system primitives, parallelism appears only, if multiple processes execute tasks simultaneously. In the following, we illustrate the possibilities provided in PRIMA for mapping tasks and services to processes [15] (cf. Fig.…”

So far, parallelism in complex-object and object-oriented DBMS has not been investigated in depth because descriptive and set-oriented query languages did not exist for these systems. However, with standardization of OQL by ODMG or SQL3 by ANSI, systems implementing these languages are ready to exploit parallel query processing strategies. In this paper, we explain differences between parallel query processing in relational and complex-object DBMS. Furthermore, we present a client~server-based system architecture that allows for fine-grained parallelism within query processing in complex-object DBMS. We investigate various strategies for mapping this architecture to processes of the underlying operating system. Finally, some measurements show the impact of these mapping strategies on query response times.

In order to achieve acceptable pelformance in enhanced DBMS different kinds of parallelism have to be enabled by appropriate implementation capabilities. The Remote Cooperation System (RCS) offers these capabilities. lt is the basic communication system of our enhanced DBMS called PRIMA. In this paper we present different implementations for RCS and an analysis of their pelformance behavior. In order to get a better assessment of these implementations, we compare our measurements to those obtained with conventional remote procedure call facilities offered by operating systems. The results demonstrate that RCS is suitable for supporting parallel query execution.
