What are some examples of SQL concurrency control implementation?
SQL concurrency control is essential for managing simultaneous database transactions. Examples include locking mechanisms, timestamps, and optimistic concurrency control.
Can you explain how locking mechanisms work?
Locking mechanisms prevent multiple transactions from accessing the same data simultaneously. There are different types of locks, like exclusive and shared locks.
What is optimistic concurrency control?
Optimistic concurrency control allows transactions to proceed without locking resources, checking for conflicts only at commit time.
What are the advantages of using timestamps?
Timestamps help maintain the order of transactions and can simplify conflict resolution by providing a clear sequence of events.
