ILE C/C++ Programmer's Guide


Database Files and Distributed Data Management Files

A database file contains data that is stored permanently on the system. The object type is *FILE.

Database files can be created and used as either physical files or logical files. Database files can contain either data or source statements.

ILE C/C++ programs access files on remote systems through distributed data management (DDM). DDM allows application programs on one system to use files that are stored on a remote system as database files. No special statements are required in ILE C/C++ programs to support DDM files.

A DDM file is created by a user or program on a local (source) system. This file (with object type *FILE) identifies a file that is kept on a remote (target) system. The DDM file provides the information that is needed for a local iSeries 400 to locate a remote iSeries 400 and to access the data in the target file.
