What are the different concurrency control methods in databases?
There are several concurrency control methods, including locking, timestamp ordering, and optimistic concurrency control. Would you like to know more about a specific method?
Can you explain how locking works?
Locking involves restricting access to data by multiple transactions to prevent conflicts. There are two main types: exclusive locks and shared locks.
What are the advantages of using optimistic concurrency control?
Optimistic concurrency control allows transactions to proceed without locking resources, reducing wait times. It's beneficial in low-contention environments.
How does timestamp ordering differ from other methods?
Timestamp ordering assigns a unique timestamp to each transaction, ensuring that they are executed in the order of their timestamps, which helps maintain consistency.
