CSC/ECE 517 Spring 2023 - E2338. Reimplement the response map hierarchy

Introduction

Expertiza Background

When someone writes a review in Expertiza, they are creating an instance of the Response class. Each Response is created based on a particular ResponseMap. The ResponseMap tells who the reviewer is (the reviewer_id), who the reviewee is (the reviewee_id), and what is being reviewed (the reviewed_object_id).

• The reviewer_id is normally a record in the Participants table, which specifies an AssignmentParticipant. However, if teams rather than individuals are doing reviews for this assignment, it may be an AssignmentTeam.
• For reviews of student work, the reviewee_id is always an AssignmentTeam. (If an assignment is set up so individuals rather than teams submit work, the reviewee will still be a 1-member AssignmentTeam.)
• For teammate reviews, the reviewee_id is always an AssignmentParticipant.
• The reviewed_object_id is normally an Assignment. But in the case of meta-reviews, the reviewed_object_id is another ResponseMap (because it is a review that is being reviewed).
