Re: UU database: problem tables

I expected that single problem may be  offered to many students, and every student may have personal solution with personal access and personal status.

Also, I suspect that status may be a part of many other ACL entries. In any given case, what entities need ACL but still not covered with ACL yet?

Looking at latest database diagram.
Wouldn't it make sense to combine topic_problems and problem_solutions
One problem - one solution after all...
Another thing (which sort of derives from this): there is no real
It's just person_problem_solutions in this case, and it contains info on
how the person
solved the problem, not on their access to it (there still will be
person_problem_acl, that
shows access of given person to given problem).
