Distributed data management (DDM)

DDM is a function of the operating system that allows an application program or user on one system to use database files stored on remote systems. The systems must be connected by a communications network, and the remote systems must also be using DDM.

DDM on the iSeries™ server allows application programs or users to:

• Access data files that reside on remote systems (target systems). The remote systems can also access data files on the local iSeries system.
• An application can add, change, and delete data records in a file that exist on a target system.
• Create, delete, or rename files on a remote system.
• Copy a file from one system to another.

When DDM is in use, neither the application program nor the program user needs to know if the file that is needed exists locally or on a remote system. Remote and local file processing are essentially handled the same way.
