Q3\\ 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, 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, name, 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 1.Design an ER diagram to capture the above requirements? 2. Mention to primary key and candidate key if it is find? 3. Show the Relationships among entities?
