The local city youth league needs a database system to help track children who sign up to play soccer. During the sign$-$up process, the parents need to provide the following information: parent's last name, first name, address, and home phone number. The children are then considered players and are assigned to teams, with each team having been trained by a coach. Players$$ information includes player's last name, first name and age. Coaches need to report their last name, first name, and home number as well. Each team will have its own name and team color.
