Set,
there's nothing inherently wrong with DDL scripts AFAIK. Maybe I'm silly,
but when I pass out an upgrade to my applications, the minor version number
increase coincides with a metadata upgrade to the database. Everytime my
applications fire up, the first thing they do is check the version of the
database. If the application is a (or more) step(s) ahead, then IB_Script
components fire up to upgrade the database and commit the changes. Since
these scripts are left in the source, it is possible then, to bring a
database several versions old up to date in one transparent step. There is,
of course a note and my users are aware that an upgrade must be done while
noone else is working on the database. But I haven't had a problem with this
strategy yet.
In Duilio's case, I would rather do it with multiple tables. Since no two
companies are allowed to see other company's data, then separate tables
would be ideal - especially since permissions would be easier to manage. But
it's his project.

Duilio,
the one thing that bothers me is that you want to do DDL from within your
application. Unlike Helen, I cannot say exactly why, but it does ring a
warning bell.

The one article that I think may get you on a better track is "An Auditable
Series of Numbers" found on
http://www.ibobjects.com/docs/ti_AuditableSeries.ZIP

Regardless of whether this helps or not, I hope you find a good solution to
your problem.
