Open publisher page 1 citations

Abstract

In order to satisfy the future demands on database processing, a new database machine termed Multi‐user Relational Database Machine (MRDBM) is proposed in this paper. It executes database operations in a parallel manner by applying distributed multiple processing units. However, it differs from other database machines using the same approach in three ways: (1) data pages rather than whole relations (or buckets) are used as the processing entity to increase processing parallelism; (2) data pages are embedded with instruction codes to reduce control overhead; (3) heterogeneous architecture is adopted to make the processing of complex database operations like sort and join more efficient. As a result of these modifications, MRDBM has better performance especially in the multi‐user environment. In this paper, we will describe how the system is designed and the current development of MRDBM.
