Opis

This volume presents the proceedings of a workshop on parallel database systems organized by the PRISMA (Parallel Inference and Storage Machine) Project. The contributors provide a survey of several aspects of parallel database systems. The second part of the volume gives an in-depth overview of the PRISMA system, which is based on a parallel machine with individual processors which each have their own local memory and communicate with each other over a packet-switched network. On this machine, a parallel object-oriented programming language, POOL-X, has been implemented, which provides dedicated support for database systems as well as general facilities for parallel programming.
