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.
