Chapter 6, Problem 6.15RQ
Explanation of Solution
Two-phase locking:
The process in which the locks are acquired during the growing phase and released in a shrinking phase is called two-phase locking.
- One way of achieving serializability is two-phase locking.
- Serializability is the process of processing concurrent transaction which can be achieved through one of the number of different means...
