What are the advantages of pessimistic concurrency control?
Pessimistic concurrency control prevents conflicts by locking resources, ensuring data integrity during transactions.
Can you explain how it differs from optimistic concurrency control?
Sure! Optimistic concurrency control allows transactions to proceed without locking, checking for conflicts at commit time.
What are some real-world scenarios where pessimistic concurrency is preferred?
It's often used in banking systems where data integrity is critical, as it minimizes the risk of conflicting transactions.
Are there any downsides to using pessimistic concurrency control?
Yes, it can lead to reduced performance due to locking, especially in high-transaction environments.
How can I implement it in my database?
You can implement it by using locking mechanisms provided by your database management system, like row-level locks.
