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:
