Quizplus · Accepted Answer

The lost-update problem occurs when two or more users simultaneously attempt to modify the same data item, resulting in one of the updates being lost. To prevent this problem, locking mechanisms can be used to coordinate and synchronize the activities of users who may be unaware of each other's actions. Data integrity and redundancy are important considerations in database management, but they do not directly address the lost-update problem. Data access is a more general concept that encompasses the use of locking as well as other techniques for controlling user access to data.
