🔒 Two-Phase Locking (2PL) Protocol Explained Simply | DBMS Concurrency Control Tutorial
Learn everything about Two-Phase Locking (2PL) – a key lock-based protocol that guarantees conflict serializability in database transactions and prevents common concurrency issues like lost updates or inconsistent reads.
This easy-to-follow tutorial breaks down 2PL step by step with clear animations, real-life examples, and diagrams – ideal for beginners and exam prep!
In this video, you'll understand:

The need for concurrency control in multi-user databases
Growing Phase (acquiring locks) vs Shrinking Phase (releasing locks)
Shared Locks (S) vs Exclusive Locks (X) and the lock compatibility matrix
Popular variants: Strict 2PL, Rigorous 2PL, and Conservative 2PL
Real life example
Deadlocks: Causes, detection, and prevention in 2PL

Great for GATE Computer Science, university DBMS courses, placement interviews, and anyone building reliable database systems!
