PRISMA/DB is a parallel, main-memory, relational DBMS that was designed and implemented in the Netherlands by several scientific and commercial research institutions. The main partners of the project were: Philips Research Laboratories in Eindhoven, University of Twente, Center for Mathematics and Computer Science , and the University of Amsterdam.
In the fall of 1986, the PRISMA project was started. The goal of the entire PRISMA project (of which PRISMA/DB is a subproject) is the design and realization of parallel hardware and software to implement the parallel object-oriented programming language POOL, and the implementation of a non-trivial application in POOL. A DBMS was chosen as an application. Therefore, PRISMA/DB was designed to be implemented in POOL and to run on the PRISMA-machine , the 100-node parallel,shared-nothing machine on which POOL is implemented.
