The previous lecture discussed Two-Phase Locking (2PL), a pessimistic concurrency control method. This lecture introduces Timestamp Ordering (T/O), an optimistic approach where transactions do not require explicit locking during data access.
The core concept of T/O uses timestamps to define a serial execution order for transactions: if TS(T_i) ...
