Create a small Sports database with two tables: Team and Athlete. The Team table should include fields for the type of team (e.g., basketball), coach’s name (both last and first), and the season the sport is most active (S for spring, F for Fall, or B for both). The Athlete table should include fields for student number, student first and last names, and type of sport. Use the same identifier for type of sport in both tables to enable the tables to be related and linked. Populate the tables with sporting teams from your school. The type of database (SQL Server or Access) will be determined by your instructor. Write a C# program that displays information about each team, including the names of the athletes.

When a selection is made or a new entry is typed, display the selection on a Label object on your form. Add a menu to the application that includes at least the menu options of Format and Help. Under the Format selection, include options of Font and Color. Wire the Font and Color options to the Windows predefined Font and Color dialog boxes so that when their values are changed, the text in the Label object displaying the saying is changed.

Another menu option closes the application. Be creative and be sure to produce an aesthetically pleasing design using options from the Format menu if you are using Visual Studio.

Write an application that allows the user to input information from both stations and make a decision as to which station offers the most economical fuel price. Test your application with 1.259 per liter against 4.50 per gallon. Once the decision is made, display the equivalent prices. (1 liter is 0.264172 gallons)

Design a solution that prints the amount of pay a commissioned salesperson takes home. The more sales documented, the larger the commission rate.
