Lock Managers

Lock managers are systems within databases that coordinate access to data to prevent conflicts and ensure consistency. When multiple users or applications try to access or modify the same data simultaneously, the lock manager manages these requests by granting or denying locks based on rules, ensuring data isn't corrupted or lost. Think of it like a traffic controller for data, directing who can read or write at a given time to keep everything orderly and accurate. This process helps maintain data integrity and smooth operation in multi-user database environments.
