Problem Statement
Antwerp University Fitness Centre is a university sport center that is responsible for running competitions among the different faculties in university. The competitions are organized into different games. Antwerp University Sport Centre needs a system to help organize and maintain records of the competitions that take place in each game. The system, in essence, needs to keep information on the participated student, their faculty, the organization of the competitions, and the competition results.

Faculties and Faculty Members
At the beginning of the game, before any competition can take place, every faculty that wishes to participate in the competition must register with Antwerp University Sport Centre. Each faculty is known by a unique name; however, for ease of reference, each is also given an ID, which is a short sequence of characters. Each faculty must provide a contact person’s name and phone number, and the faculty’s address and fax number.
In registering with Antwerp University Sport Centre, a faculty submits a list of their students who will participate in the game’s competitions. During the game, additional students can be registered while the game’s competitions are in progress. The date a student registers for competition is recorded. Those who register when the faculty is registered have the first day of the season as the registered date. For each student, Antwerp University Sport Centre requires their name, date of birth, gender and phone contact. Antwerp University Sport Centre then issues them with a unique ID.

Meets, Competitions and Events
The competitions are organized into a series of games. Each game is held in the course of one day at one particular venue. Each game consists of a series of events (matches) run on different venues. Each type of event has a code and a descriptive name that is also unique.

A sample of the result of a competition in a meet is shown below.

Meet FC01
Date: 10 jan 2020
Game: Football Competition

Event Scores

ID	Match
E01	Faculty of Education	0	Faculty of Dentistry	0
E02	Faculty of Engineering	2	Faculty of Science	2

Each meet is identified by an ID (e.g. “FC01”), and has a name (e.g. Bosuilstadion Stadium). A competition within a meet is identified across the system by the combination of the meet ID and the division code.

Teams in Competitions
When a faculty registers for a meet, the faculty enters a subset of its students. This subset is known as a team. When a team is at a meet, it must participate in all the events of that competition. A team must have the same set of members competing for each event within a competition.

Scoring
Each event in a meet has a referees panel assigned to it. These people are qualified to give scores for this event. Antwerp University Sport Centre (and the system) maintains a list of referees including their personal details (name, phone number) and the types of events they are qualified to judge. For ease of reference, each referee is given a unique ID.
Each referee write a report on the performance of each team on an event. The best team will in the event will be nominated for the prize of best team in the game.
The season’s ranking of the teams depends not only on their total scores for the meets but also on other factors, for example, the team sizes and the best performances of the members for various events.
