Accessing Database Files
Database File Support
Database files are an integral part of the AS/400 that allow customers to
store and retrieve their mission critical data. Database support is
integrated into OS/400 through the DB2/400 feature. Web Server/400 provides
support for returning Web content that is contained in AS/400 database files.
- Source Physical Files
- Source physical file members are normally used to store program source
and file definitions. Source physical file members can also be used to store
Web content that is in plain text form or marked up using HTML.
Samples are provided
to demonstrate retrieval of documents from source physical files.
- Physical and Logical Files
- Physical and logical files are used to store application/business data on
the AS/400. Web Server/400 supports returning formatted data (including HTML)
that is stored in keyed or non-keyed database files. The server also supports
querying data that is stored in keyed files. Spooled files that have been
copied into database files can also be returned.
Samples are provided
to demonstrate retrieval of data from database files.
- Distributed Data Management Files
- Web content can be returned from distributed data management (DDM) files
that reference remote source physical files, physical database files or logical
database files. Data is returned from the remote file as if the file was
located on the local system. The type of remote file the DDM file points to
determines the options that are available.
