Data-volume and frequency-of-use statistics are not critical inputs to the physical database design process.

  • A.
    True
  • B.False

Answer: B

Correct answer: False

Data volumes and access frequencies are among the most critical inputs to physical design: they decide which tables are large enough to warrant indexing, which queries run often enough to be worth optimising for, and where the storage and contention will fall. Without them the design decisions are guesses.
