Controls that do not allow users to update the same database record at the same time are examples of: a) Data integrity controls b) Data processing controls c) Concurrency controls d) Privacy controls

The correct answer is option c) "Concurrency controls".

Explanation:

In database management systems, concurrency controls are defined as procedures that allow the management of multiple operations at the same time, without causing conflicts in any of them. Concurrency controls do not allow users to update the same database record at the same time because that will cause conflicts in simultaneous procedures. If more than one user is updating the same datable record at the same time, multiple operations could not be managed simultaneously.
