In this paper we propose a new approach to data distribution and load balancing in
multiprocessor database systems with hierarchical architecture. A model of hierarchical
database multiprocessor architecture is described. This model is called DMM. It allows us to
simulate and analyze various multiprocessors configurations. An important subclass of
multiprocessor hierarchies is considered. We call it symmetric hierarchies. For the symmetric
hierarchies, a new strategy of data distribution is proposed. This strategy is based on the …
