To the experts...!

I have a question for some of the experts out there. I have a database, I
created a backend database importing the tables to this particular backend
database. Then I created 8 frontend databases, I linked the tables from the
backend to the frontend. No problems there. Since then I updated some of the
forms in the main database. How can I update the frontend databases without
having to go go one by one I re-create the changes to each one.

Please help.

Sincerely,
JM
