Great question. I debated for awhile, completely forgot the way data is stored in pages, and got the answer wrong. But I really enjoyed reading why 🙂

Ah, correctly answering one of Hugo's questions is a great start to the weekend! I will savor this feeling, as it may very well months until it happens again.

Great question, Hugo.

Thanks, all, for the kind words. I figured a not-too hard yes/no question would make for a nice change of pace. (It being scheduled on a friday is not my doing, though).

The next question in this series (which will be a tough one, I hope) is still being prepared, but I do have another (unrelated) question scheduled for next week - so brace yourselves! 😛

I have attempted "table space usage" questions 1,2 and 3 in sequence, but the answer for question 3 is mentioned in discussion of question 2 :-).

"In the real world, one would never calculate the data size to the exact page number."

I think that quote in the discussion on question 2 is about the lack of practical application. And that is true. In a real database, I want to have a good estimate about the data size I can expect, but I truly am not bothered by just a few pages more or less. However, the table designs I used in question 1 and 2 were such that an exact calculation is at least possible.

For question 3, the table design is such that based on the given information it is impossible to do this exact computation - even if you would want to.
