Distributed Data Management
     
         (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.
