Hello,

This is my first message on this list. Hello to everybody! :-)
I'm new with Delphi/Firebird (long time from DOS) and there is some
things that I does not understand.
I'm developing a Win version of my software and learning the concept
of Client/Server.
The use of a foreing key is only necessary when we need cascade
updates/deletes? Instead of this cases, we can use the JOIN statement.
There is improvement using FK?
Why I can't create a foreing key after the tables has some data ou
triggers? There is a special rule for this?

Thank you all for the attention.

Platform: WinXP Pro, Delphi 6 Pro (SP2) and FireBird 1.5.
