Validation-Based Concurrency Control

Validation-Based Concurrency Control is a method used in databases to manage how multiple users access and modify data at the same time. Instead of locking data while it's being worked on (which can slow things down), this approach allows users to make changes in a separate space. Before finalizing, the system checks if any conflicting changes were made by others during that time. If there are no conflicts, the changes are accepted; if not, the user may need to retry. This method enhances efficiency while maintaining data accuracy and consistency.
