Example: Accessing files on multiple systems with DDM

This topic contains a figure that shows the relationships among the client system, its DDM files, and two server systems.

One server system is a System/38 and the other is a System/36. Each system has DDM installed.

The user program running on the client system is shown accessing three files: FILEA, FILEB, and FILEC. FILEA, located on the client system, is accessed using only local data management. On different server systems, DDM file FILEB corresponds to remote file FILEX and FILEC corresponds to remote file FILEY. When the program opens FILEB and FILEC, DDM allows the program to access the corresponding remote files as if they were on the client system. Only the person who defines the DDM files needs to know where each file is located or what the file name is on the remote system.
