I agree. The other approach I thought is to enter a "dummy" record with blank entry in the primary table and "hide" it from the user. But maybe I will learn to live (code) with NULLs instead of empty entries.
Speaking about triggers. Do I understand correctly that specifying foreign key constraint with cascade option is pretty much the same as used to be done with triggers to update foreign keys?
