Ruby on Rails

Check out Fred's earlier example. Using the count of courses with only
one courses_times row in conjunction with the having clause you can
filter out courses scheduled on more than one day.

The only potential problem I could foresee with this would be if a
course could be scheduled for multiple times on the same day. But
that's not reflected in the data model you posted so it shouldn't be
an issue.
