Row-level locking is a mechanism used to handle concurrent access to a shared database. When one user is updating a record, row-level locking prevents other users from accessing that specific row, thus avoiding conflicts and ensuring data integrity. This way, multiple users can access the database simultaneously without creating any inconsistencies.
