A children’s sports league is currently keeping its records on paper and has asked you to design a data model so they can track their information in a database. For each child, the league has: first name, last name, age, address, whether a boy or a girl, and a note to indicate asthma or other medical conditions. They tell you that first and last name is good enough to identify a child. Each child has his or her own emergency contact, and for each emergency contact the league has: name, phone number, and relationship to the child. The league intends to use this database for many years, and over time each child will be on multiple teams. Of course, each team will have several children on it, and the league tracks the following about each team: sport, team name, coach’s name, number of wins, number of losses, and number of ties. For each child-team assignment, the league tracks the jersey number and position the child plays on that team. Create the entity-relationship diagram (ERD) for an appropriate data model. Be sure to indicate the identifier for each entity (if any) and the relationships between entities using the crow’s-feet method.
