A stepwise approach to distributed database systems by database machines

摘要

Database machines are good components to compose distributed systems along with personal computers and local area networks. Distributed database systems by those machines could be cost-effectively respond to various user's requirements. A stepwise approach to distributed database systems by database machine FRENDs is presented in this paper.

At first, the database machine FREND is introduced. Then a stepwise extension to distributed database systems is explained. In order to execute queries efficiently, distributed view management method is proposed. Particularly, pipe line join method is explained and shown to be effective if certain conditions are assumed. Finally consistency problem of view data is discussed.
