-There exist three different tables to hold all graduation information of a student.
-One global submission table called `Submit` writable by all students and two individual ones per student.
-The separation is needed for the different required permissions to access the stored data.
-All individual tables use the following naming scheme `${StudentId}${Purpose}`.
-
-The section containing the student's tables is only available to teachers and the student.
-
-### Submit Table
-
-The submit table is writable by all students and is used to track observation requests from students.
-It is configured to require approval to publish entries.
-This ensures that entries are only readable by the submitter and the teachers.
-Entries are simply never approved.
-
-### Public Table
-
-The public table tracks all graduation changes known by the student.
-The included information are sufficient to render a student's profile.
-
-Changes can be submitted by any teacher.
-Each change is valid until a subsequent change renders it obsolete.
-
-Changes include points and level changes.
-
-### Shadow Table
-
