What kind of relationship do we find here?

If each student can do the evaluation several times (attempts), then we have a 1 to N relationship between students and attempts.

Therefore, in that case the student_id goes in the attempts table.

Since there is no way for several students to make the same attempt (but if the same evaluation), then we can ensure the relationship 1 to N.

In that graph that you show, however, there are many relationships that are not understood.

It is assumed that an evaluation is unique, and is not related to any student. It could be related to a subject. Therefore, there are illogical relationships within what you show.

## IMPORTANT NOTE

It is important to understand that the relationships in a database are given by the rules of the business. There is no one way to make relationships without knowing precisely the rules that business has. One can suppose how it should be, but without knowing if, for example, the student can make more than one attempt, it is impossible to know if the model is correct or not.
