INFO20003 A2 S1 2019 1INFO20003 Semester 1, 2019Assignment 2 – SQLDue: 6:00pm Friday 3 MaySubmission: Via LMS https://lms.unimelb.edu.auWeighting: 10% of your total assessmentMelbourne Touch RugbyThe Melbourne Touch Rugby competition is a 6-player-a-side competition for men’s, women’s andmixed teams (a mixed team has a minimum of 3 women and maximum of 3 men on the field at anytime). Players must be registered with a club to play in the competition and players can only beregistered for one club at a time.Currently there are 8 rugby clubs participating in the competition, which began in 2017. Each club hasthree teams – a men’s team, a women’s team and a mixed team. The men’s competition is known asthe Dewar Shield; the women’s competition is known as the Williams Plate; and the mixed teamscompetition is known as the Bingham Trophy.A season is the set of games played in a competition in a calendar year. Each season consists ofrounds in which every team plays a game.Even though each game is played by 12 players (6 from each team), a team is not a fixed group of 6players. The team officials choose 6 players from their club, or possibly even from another club, toplay for that team in a game. As such, the composition of a team varies from round to round.If for any reason a team is unable to organise enough players to play a game, that team will forfeitthe game and their opponents will score a “walkover”. A walkover awards 28 points to the team whoscores a walkover and 0 points for the team who forfeited. If a game is cancelled (e.g. due to extremeheat, unsuitable playing pitch), no score is recorded against either team.INFO20003 A2 S1 2019 2The Data ModelFigure 1: The ER Model for Melbourne Touch RugbyAssignment 2 SetupA dataset is provided against which you can test your solutions to the assignment.
