Distributed Data Management
<protocol, database> (DDM) An IBM data protocol
architecture for data management services across distributed systems in an SNA
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.
