Discussion
The design guidelines and priorities for read-only databases are different because read-only databases are never updated.
Answer: A
Correct answer: True
Because a read-only database is never updated, modification anomalies cannot occur, and the chief reason for normalizing disappears. What remains is the cost of joins, so the priorities invert: denormalized structures that answer queries in fewer joins are preferred, and the design is judged on retrieval performance rather than on update integrity.
