Discussion
Creating a read-only database is a task that is ________ assigned to beginning database professionals.
Answer: B
Correct answer: commonly
Building a read-only database from a set of extracted tables is a well-defined, low-risk task with no update logic to get wrong, which is why it is a common first assignment. The design priorities are different too: since nothing will be updated, modification anomalies cannot arise and the tables are often deliberately left denormalized for speed.
