The system wide catalog is more than just for SQL.  You can QUERY or write
RPG programs against the following system files.

   QADBIFLD contains a list of all fields for all PFs and LFs.  (DSPFFD
information.)

   QADBKFLD contains the keys for all PFs and LFs.  (DSPFD TYPE(*ACCPTH)
information.)

   QADBFDEP contains all PFs and LFs whose existence depends on another
file.  (DSBDBR information.)

   QADBXREF contains a list of all PFs and LFs.

These files do NOT contain information from DSPFs or PRTFs.
