Distributed Data Management

protocol, database (DDM) An IBM data protocol

architecture for data management services across distributed

systems in an SNA environment.

DDM provides a common data management language for data

interchange among different IBM system platforms.

Products supporting DDM include AS/400, System/36,

System/38 and CICS/DDM.

On the AS/400, DDM controls remote file processing.

DDM enables application programs running on one AS/400

system to access data files stored on another system

supporting DDM. Similarly, other systems that have DDM can

access files in the database of the local AS/400 system.

DDM makes it easier to distribute file processing between two

or more systems.
