The following information that models a male rugby squad, the games they play, and the players in each team. In the design, we want to capture the following:

Each team has many players, and each player belongs to one team. Each player has a number $($unique identifier$),$ name, $D_2{B}_0$ start year, and jersey number that he uses.

Teams play matches, in each match there is a home team and an away team. The match takes place on the home grounds of the host team.

For each match we need to keep track of the following:

The date on which the game is played

The final result of the match

The players participated in the match. For each player, how many try$\text{'}$s he scored, whether or not he was awarded a yellow, and whether or not got a red card.

During the match, one player may substitute another player. We want to capture this substitution and the time at which it took place.

Each match has exactly Four referees. For each referee we have an ID $($unique identifier$),$ name, DoB years of experience. One referee is the main referee and the other two are assistant referees and the last is a Television Match Official $($TMO$).$
