D Correct answer
Explanation

The four key characteristics of data warehouses are: subject-oriented (organized by subject), integrated (consistent data from multiple sources), time-variant (historical perspective), and NON-VOLATILE (not updateable). Data warehouses are designed for read-heavy analytical queries, not transactional updates. Updateable is the characteristic that does NOT apply to traditional data warehouses.
