Correct Answer: Optimistic locking
- Step 1: Understand what concurrency control means. It is a way to manage how multiple users access and modify data at the same time.
- Step 2: Know that there are different methods of concurrency control, such as optimistic locking and pessimistic locking.
- Step 3: Recognize that data warehousing often involves many read operations (looking at data) and fewer write operations (changing data).
- Step 4: Learn that optimistic locking is a method that works well in situations where reads are more common than writes.
- Step 5: Conclude that optimistic locking is the concurrency control method commonly used in data warehousing.
