True!

And cross-code lookup tables can make otherwise very large 'bytes on 
disk' rather small overall.

         Z3  in common_names.dbf  African Pygmy Zebra
         Z3  in zoological.dbf    ThatBigLongNameNobodyCanPronounce

          Stored in MAIN dbf along with head count, bin number and
            "Zoo" (location) code to use the Zoo thing.

Pgm knows where to find the dbfs and which fields to match.

But then everybody already knew that.
