Optimistic Concurrency Control

Optimistic Concurrency Control is a method used in databases to manage multiple users accessing the same data at the same time. Instead of locking data while it's being modified, this approach allows users to make changes freely, assuming conflicts are rare. Before finalizing changes, the system checks if anyone else has updated the data since the user started. If not, the changes are saved; if there’s a conflict, the user must revise their work. This approach enhances performance and user experience, especially in environments with many read operations and fewer writes.
