Design question from newbie
Hello MySQL users,
I've just started out with MySQL, and have already bought and read Paul
DuBois's excellent book. Nevertheless, I'm not exactly sure how to start
making a database for all the data I have.
What I have are responses from questionnaires administered to several
organisations over a number of years. While the questionnaires are very
similar in many ways, they are certainly not identical. I wish to calculate
what common statistics I can for the purpose of longitudinal comparisons
within and between organisations.
The raw data looks a bit like
ID,YEAR,SEX,AGE,RATING A,RATING B, ...
1,2001,1,3,7,6,...
As I said, not all organisations were asked the same questions so I can't
just put the data in directly
The only way I can see of dealing with this is to create tables like
ID,QUESTION,RESPONSE
1,"YEAR",2001
1,"SEX",1
1,"AGE",3
1,"RATING A", 7
1,"RATING B", 6
...
This doesn't strike me as very smart. I would greatly value anyone's advice
on dealing with data that is similar in many respects but different in
others. Thank you very much.
Regards,
Andrew C. Ward
