The question might well belong in the database; it probably does, but it depends on what you are modelling. It does *not* belong in the table of responses. If you put it there, each row of answers for a questionnaire would have the same questions text which is redundant (or silly).

Note that database and table are two different things. You might have:
Responses to Questionnaire 58 Table
-- Lame Column Name -- Friendly Column Name ---- Question 1 Response text Name Question 2 Response int Age at Time of Questionnaire Question 3 Response text Opinion of Prime Minister Question 4 Response text Opinion of Opposition Leader
