You are to assume the role of a database analyst that has been assigned to develop an entityrelationship diagram ERD for a neighborhood swim team league. Each swim team is made up of a large number of swimmers. For each swimmer they want to know the swimmers name, address, phone number, email, and date of birth. Each swimmer can be a member of only one team. Each team also has one captain.
The team competes in meets many times during the season. Meet information includes date, location and type of meet. Many teams can compete at each meet. For instance on Saturday June th Hunters Green, Arbor Green, Meadow Pointe and Brookfield competed at the Hunters Green Fathers Day Swim meet.

The key part of this database is to track individual times, individual places, individual points, and team points. See the attached score sheet from a meet to understand the type of data you need to collect. For each event a swimmer competes in they receive a time, and a point amount eg first place points, second place points, etc. To determine which team wins the meet individual points are summed. The team with the most points wins the match.
