Are you certain that performance should be your primary concern here?
I prefer to design databases with separate tables of tightly coupled information, then
LEFT JOIN them as needed. This makes maintenance much easier, and may also be a
performance plus, due to locality of reference issues.
Only when I'm certain that this form (4NF? I forget) is negatively impacting performance
do I bother optimizing to 3NF by permanently joining tables.
