In my application layer, I'll probably end up automatically adding the student-course and tutor-course relations to support a particular student-tutor-course tuple. However, as I mentioned in another comment, it is possible that Emma will tutor Alex in Chemistry this semester, but then realize that actually she hates tutoring Chemistry next semester. Thus I'd want to remove her from her assignment to Chemistry without erasing her historical assignments. I guess soft deletes could support that too. | |
