A software organization is presented to provide for data definition and manipulation in a distributed data base management system. With the mechanism for distributing the data base proposed here, the physical location of the data is transparent to the user program. A Device Media Control Language is specified for the assignment of control of and access to a data base area to a set of processors. Procedures for reassignment of the control and access functions as well as the transfer of data between processors are provided. The basic hardware and software requirements for a computer network capable of supporting a distributed data base management system are discussed along with a specification of the software required for a processor in a distributed data base network.
