Distributed Data Management
Jump to user comments
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,
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.
