    - When the database checks a constraint, it signals an error if the constraint is not satisfied.

    - You can defer checking the validity of constraints until the end of a transaction.

    - When you issue the SET CONSTRAINTS statement, the SET CONSTRAINTS mode lasts for the duration of the transaction, or until another SET CONSTRAINTS statement resets the mode.
