Explanation:
Now, let's define the relationships:
- A "Player" plays for a "Team," and a "Team" can have many "Players." This is a one-to-many relationship.
- A "Game" involves at least ten "Players." This is a many-to-many relationship between "Game" and "Player."
A "Game" is
associated
with a "Team," where the "Team" is one of the participating teams in the game. This is also a many-to-many relationship between "Game" and "Team."
To capture the business rules and constraints:
1. Maximum and minimum player limits for a "Team" (between 13 and 20 players) can be
enforced
in the application logic or as part of a semantic integrity constraint.
2. Ensuring that a "Player" can play for only one "Team" can also be enforced in the application logic or using a unique constraint on the "SSN" attribute in the "Player" entity.
3. The requirement that a "Game" involves at least ten "Players" can be documented as a business rule.
