Quizplus · Accepted Answer

The lost-update problem occurs when two or more users try to update the same record simultaneously, resulting in one user's changes being overwritten by another user's changes. This is a unique issue in a multi-user database environment where multiple users can access and modify the same data at the same time. Redundancy, locked file, security, and data integrity issues can exist in both single-user and multi-user environments.
