Question

Quizplus · Accepted Answer

Resource locking, also known as record locking, is the technique used to prevent multiple applications or users from obtaining copies of the same record when it is about to be changed. This ensures data consistency and prevents lost updates. Serialized reading, concurrent processing, and block factorization are not related to preventing multiple applications from obtaining copies of the same record. Lost updating is a data integrity issue that occurs when two or more transactions attempt to update the same record concurrently, and one update overwrites the other.
