Its pretty clear with business case!
Great explanation!
I think the the notes that you have mentioned are converse . BeforeTrigger would be used to check other tables referential integrity checks and After Trigger would be used to check its own constraints and referential checks
Is after trigger only used for create or insert but not other update delete etc ?
What's the use of background music ???

Thanks for your valuable feedback.
