Subject: Student Internships Tracking System

Question: � Student Internships Tracking System:
You are asked to design a data management system for automating the tracking of summer
internships in a university at a particular year (see Bilkent Internship Web site as an example).

The system should keep track of secretaries, faculties, departments, students, companies, quotas, assignments, announcements, etc.

A secretary has a name and password to login to the system.

There are several faculties, each with a unique acronym (e.g., ENG for engineering) and a name.

Each faculty has several departments, again with a unique acronym (e.g., CS, IE) and a name.
Each faculty has a secretary and a secretary works for only one faculty.
A secretary may provide announcements, which has a unique id, date and announcement text.
A student has a unique id, name, year, CGPA, etc. and is associated with a single department.
A company has a unique name, as well as an address and a city.
A company may be either a �registered company� or a �self-found company�, which means it is found by the student.

For a self-found company, the contact person name and title must be stored, as well.
Each registered company have one or more units, which again have a name (i.e., there is at least
the �main� unit, if no other units exist).

A unit of a registered company opens a quota for possible student interns to be accepted.

A quota has a unique id, capacity, contact person, an application deadline and an internship period.

A quota may be associated with a department or faculty, if it is restricted to students in particular faculties or departments.

Students apply for quotas (until the application deadline).
Of course, a student may apply several different quotas, and vice versa.
After the application deadline, the secretary decides (or runs a random assignment) of students to quotas.
A student may be assigned to only one quota whereas several students may be assigned to the same quota.
An assignment has approval deadline, until which a student can accept or reject the quota, and a status.
If (s)he accepts, the status of the assignment is changed to �ACCEPT�.
If rejected (either directly by student or automatically once the approval deadline passes), the secretary
can see this �open� quota and assign it to another student.
Instead of applying for a quota, the student may have found a company for his/her internship
(i.e., self-found company).
If this is the case, the system directly assigns the found company to this particular student.
Again, a student may be assigned only one such company, whereas the company may hire several students.
