The Equi-Join Operation on a Multiprocessor Database Machine: Algorithms and the Evaluation of their one relation. In this paper, a large set of parallel algorithms for implementing the equi-join operation on a multiprocessor database machine called MIRDM (.chigan .elational .atabase .achine), is presented. An outline of a study for the performance of the proposed algorithms in carrying out the eq

A Technique for Analyzing Query Execution in a Multiprocessor Database Machineed. The starting points are the parallel algorithms implementing the relational operators in the DBM in question and the query to be executed. A structure, called query execution graph, is obtained by the analysis of this information. A query execution graph is the detailed description of the operat

Hither Hundreds of Processors in a Database Machiners of processors in a database machine, the I/O bandwidth of the underlying storage devices must significantly be increased. One way to accomplish this is to use multiple parallel disk units. The main problem with this approach, however, is the lack of a computational model capable of utilizing any
