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).

Problem Statement

We are refactoring the code which are being implemented previously for Re-implementation of response map hierarchy (E2314[[1]]). Some of the changes which are being pointed out till now are as follows-

• In the previous re-implementation, some of the methods are defined in class level which can be modified to instance level methods for better functionality and adhering to the Object Oriented Design principles.

• Few of the methods are also present in the existing project which should be implemented in other classes according to their functionality and for increasing coherency of the classes.

• Some of the methods also needs to be renamed in this refactoring process for better understanding of the developers who will be working on the project later on.
