What are some examples of concurrency control in SQL?
Concurrency control in SQL ensures that database transactions are executed in a safe manner. Examples include locking, timestamps, and optimistic concurrency control.
Can you explain how locking works in SQL?
Locking prevents multiple transactions from accessing the same data simultaneously. There are different types of locks, like shared and exclusive locks.
What is optimistic concurrency control?
Optimistic concurrency control allows transactions to proceed without locking resources, checking for conflicts only before committing.
How do timestamps help in concurrency control?
Timestamps assign a unique time to each transaction, helping to determine the order of operations and resolve conflicts.
