Sorry to not reply to this sooner. I was waiting for someone else to do it,
which maybe they did privately.

This would depend entirely on whether there is an ODBC driver for .dbf files. I
haven't looked for one myself. You might check the unixODBC site and ask there.

I'll take your word for this. :-)

This depends entirely on how you set up your queries. A one-to-many

to whether this relationship is enforced by the business rules of the database
itself or just your use of it via queries and such.
