Assume we have the following application that models soccer teams, the games they

play, and the players in each team. In the design, we want to capture the following:

  • We have a set of teams, each team has an ID (unique identifier), name, main

stadium, and to which city this team belongs.

  • Each team has many players, and each player belongs to one team. Each player

has a number (unique identifier), name, DoB, start year, and shirt number that he

uses.

  • Teams play matches, in each match there is a host team and a guest team. The

match takes place in the stadium 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 goals

he scored, whether or not he took yellow card, and whether or not he

took 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.

Design an ER diagram to capture the above requirements
