Re: Latest DB schema
The problem is solved, if solution is presented and signed by some teacher.
While placing the signature is trivial (another table with id and two references, to solution and to teacher), we still have to think on how to enforce the "teacher" role. Is it one of the ACLs for the problem?

>> Also how do we know if a problem was "solved"/"not yet solved" by student?
