If the SQL tables are missing text/headings, it's because the
programmer that created them
didn't use SQL's LABEL ON  to add them:

e.g.  label on column table (field text is 'text')   For the
field/table/library text
      label on column table (field is 'Each line is 20 characters
long, fixed.')

So there's no advantage to DDS created tables over SQL for this
purpose, save that the
column heading for SQL is one long 60 character field divided into 3
20 character lines
(if I recall correctly)
