When should I use timestamp versus lock-based control in databases?

What are the main differences between timestamp-based and lock-based control in databases?

Timestamp-based control uses timestamps to manage transactions, while lock-based control uses locks to prevent concurrent access.

In what scenarios is timestamp-based control more beneficial?

Timestamp-based control is beneficial in high-concurrency environments where deadlocks are a concern, as it avoids locking.

Are there any downsides to using timestamp-based control?

Yes, timestamp-based control can lead to issues like cascading rollbacks and may require more complex management of timestamps.

When should I prefer lock-based control instead?

Lock-based control is preferable when data consistency is critical and the overhead of managing locks is acceptable.
