Project Description

Natural Sciences and Engineering Research Council of Canada (NSERC) would like to build a system to maintain grant applications. There are three users in the system, i.e., industry researcher (Iresearcher), academic researchers (Aresearcher), administrators (Administrator). The system stores a users basic information such as name, password (pw), and unique id (id).

Each application is developed by a team of at most ten applicants, it also has a unique id (id), description, name, and score. Only researchers can be valid applicants. A team has a leader and a set of members. A team leader can add/remove new team members and create new applications. Each application will be reviewed by a set of reviewers and a reviewer can be of either an academic researcher or an administrator. Only administrators can assign reviewers to an application. A reviewer can give numerical marks to an application that they are assigned. An applications score will be the average of marks from all the reviewers of the application.

We also provide a test case, i.e., TestApplication.java, which contains some implicit constraints regarding the logic of the project to be designed. Please read the test case carefully. Note that, you are not allowed to modify the test case.

Below is the test file:
