The description file that is called using the

 -t

customizing functions:

–

name mapping of database tables and definition of the concrete storage space required
by tables (section 1 on page 35),

–

fragmentation of a database table (section 2 on page 37),

–

name mapping of views (section 3 on page 37),

–

versioning of the database (section 4 on page 38) and

–

access privileges for tables and views (section 5 on page 38).

The specification of this file, and of all entries in it, is optional.

supported:

#

The meaning of the individual lines as well as the necessary columns are now described
for each customizing function.
