Creating an Entity Relationship Diagram

A tennis league would like to restart operations after the Covid-19 lockdown. They need to keep
track of parents, players and coaches in order to closely monitor everyone. A parent may register
multiple players and each player can be registered by more than one parent. Each player belongs
to exactly one team and a team has 15 or more players. Each team has multiple coaches but a
coach is only assigned to 1 team. The information that must be captured about parents include
their TRN, name, address, telephone number. Information captured about players include their
name, date of birth and id number. Information captured about the coach includes their TRN,
name and telephone number. Information captured about the teams includes their name and color.
