How does the two phase protocol ensure serializability in database schedules?
Ans: A transaction is termed to follow the two-phase locking protocol if all locking operations precede the first unlock operation in the transaction. Such type of transaction can be divided into two phases: and expanding or growing (first) phase and a shrinking (second) phase. The two-phase locking protocol makes sure serializability in database schedules. Refer any transaction.
