A Database Computer Architectures Performance Evaluation System (DACPES)

Abstract

The design and implementation of a database computer architecture performance evaluation system (DACPES) are presented. DACPES is a simulation tool which can be configured to evaluate a class of parallel database computers (DBCs), which have shared-nothing architectures, use data flow query processing strategies, and support object-oriented databases. DACPES can be used to simulate concurrent multiple query processing in a parallel DBC under varying conditions. The functions and design issues for each of the modules of DACPES are discussed and a case study of the evaluation of an object flow computer using DACPES is presented.<>
