Recent and foreseeable advances in the technologies of microprocessors and computer communications imply the viability of a new architecture for Data Base Management Systems which should develop into an attractive tool for many applications of distributed systems. A description is given of a micro-DBMS called UNITY whose characteristics, as tested in one application of a working system, already approach those needed for use in certain applications. The command structure, hardware vehicle, and performance of UNITY are discused, together with plans for current and future improvements.
