Abstract
In this paper we present a knowledge base for the generation and optimization of query execution plans for parallel database systems. This knowledge base builds the basis of a novel extended blackboard architecture for the optimization of parallel query execution plans, which is based on a bottom-up building block approach. It allows to find (near) optimal execution plans out of a possibly huge search space in reasonable time
