I for got to add the question... :)
delete restrict - maybe (for schools) , so does not affect the students_ori
table
update cascade for the courses table
delete cascade for both table school and courses for the contacts.
 am I missing any constraint?
by the way is there any possibility of having an Inheritance?

regards
Mar
