In Computer Science, in the field of databases, non-lock concurrency control is a concurrency control method used in relational databases without using locking.
There are several non-lock concurrency control methods, which involve the use of timestamps on transaction to determine transaction priority:
- Optimistic concurrency control
- Timestamp-based concurrency control
- Validation-based concurrency control
- Multiversion concurrency control
- Snapshot isolation
