Explain how a DBMS breaks a deadlock.
What will be an ideal response?
To break a deadlock, the DBMS chooses one deadlocked user to be the victim. For the victim's transaction, the DBMS undoes all completed updates, releases all locks, and reschedules the transaction. Using this method of handling deadlocks, the user notices only a delay in the time needed to complete the transaction.
