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.
