Graph & Tree-Based Locking Protocols | DBMS | Lec. 60

In this lecture, we study Graph-Based and Tree-Based Locking Protocols, advanced techniques in concurrency control used to ensure deadlock-free and efficient transaction execution.

These protocols provide alternatives to 2PL with better control over locking order.

Graph & Tree-Based Locking

📌 Topics Covered

• Limitations of basic locking protocols
• Graph-Based Locking Protocol
• Tree-Based Locking Protocol
• Rules of Tree Protocol
• Differences from 2PL
• Deadlock-free properties
• Examples and problem-solving approach

🎯 Why this topic is important?
These protocols help in avoiding deadlocks while maintaining consistency in concurrent transactions.

🎯 Important for:
GATE CSE (Not in GATE DA)
Concurrency Control
Transaction Management
