One solution that I proposed was to create (a) separate table(s) for each
survey's responses, with each column being a response.
I have seen a different approach in operation
each record was one question, each column was a respondent. As the
number of choices was usually below 16, it was possible to store 2
respondents in a column, by using bit-masking.
Worked quite nicely!
