Resumo

To meet the increasing demand for the speedup of relational database processing, we are developing a prototype of HDM (it stands for a High Speed Database Machine). HDM is a relational database machine which has a simple structure with five 32-bit microprocessors, Motorola’s MC 68020s. HDM can execute relational database processing very fast by the parallel processing and the best suited disk access method etc. The subset of SQL which includes almost all the basic functions is implemented on the HDM. It is still being developed, but the performance evaluation about selection, projection and join queries without indices has proved that HDM can execute these queries fairly faster than some other relational database systems. In this paper, we present the hardware and software design of HDM and the results of the performance evaluation.
