A special purpose Data Base Machine (DBM) designed to translate queries between data models is examined.The DBM will provide a means of direct communication between different DBMSs in a distributed database system. The design ut~ILzes the concept of parallelism to handle simultaneous queries and to improve the performance of the translation with respect to cost and time.The components of the DB~ are described and an e~ample is provided to illustrate the stages of the query translation utili~in~ the proposed DBM.
