ZSS DBD Training/DBD Files

ZSS DBD Files

ZSS Files were previously covered and will not be covered again here. However, a list of the relevant files and their functions is listed. Where a file is system dependent, it will have an nnn in its name. This means the system number is part of the file name.

The following files are used in the DBD process:

XDFnnn

This is the database definition file for the particular system.

DTFILE

This is the data translation file for all systems.

XFFILE

This is the database synchronization file.

XTSnnn

This is the database online source inquiry file.

XDSnnn

This is the sequential edited database source file.

ZODnnn

The database update process also updates this, the online help/documentation file. The online help file includes data translation values, so must be updated whenever the DBD update process is run.

NAMEFL

The institution file is also used for read only in the DBD process.

ZSFILE

The global screen file is used in the DBD process. Each screen has data elements attached to it. If a data element on a screen is deleted during a DBD cycle, problems can ensue. Part of the DBD process is to make sure that does not happen.
