Question

Basketball is one of the most popular sports in the United States. Basketball tournaments consist of games between two teams at various stages (league, playoff, final, etc.). Each individual game in the tournament is played between two competing teams played at a specific city or stadium with a certain capacity, and attended by a number of spectators. The matches may also be televised on a TV channel, and viewed by an estimated number of TV viewers. During each match, the teams typically play two halves (which may be further divided in quarters depending on the tournament). Players score points, commit fouls and perform blocks, rebounds, and assists. Each match ends with a score with the team with the higher score being the winner. Players play for a team and have a position and a jersey number in addition to physical attributes like weight, height, birthday, etc. Players may switch teams from one season to the next. In our scenario, let's assume that they do not switch teams mid-season. Each team has a support team with at least a coach, assistant coach, and physio.

Make sure you come up with at least 3 attributes for each entity.
