What is optimistic concurrency control?
Optimistic concurrency control is a database management technique that assumes multiple transactions can complete without affecting each other.

Unlike pessimistic control, which locks resources, optimistic control allows transactions to proceed without locking, checking for conflicts at commit.
What are the advantages of using optimistic concurrency control?
The main advantages include improved performance in low-contention scenarios and reduced locking overhead.
Can you give an example of where it's used?
