Student case competitions: Your company sponsors case competitions between teams of college business students. You plan to hold dozens of different regional competitions at various dates and at various locations around the country. For each competition, you want to store a name, the planned date of the competition, the name of the venue, and the address of the venue. For each participating college, you want to store the college name, a contact phone number, and a contact address. Each team can participate in only a single competition, but each college is allowed to send more than one team to a competition. Each team is assigned a number, which is unique within the competition in which it is competing, but not among all teams: for example, two different teams could both have team number 3 if they are in different competitions. Each team also gives itself a name; you want your database to store both the team name and number. Finally, each team consists of more than one student; for each student, you want to store a first name, last name, middle name/initial, date of birth, major, and expected graduation date. All students on a given team must come from the same college, and each student can be on only one team.
