(zipped files)

Your first interactive design assignment in this course concerns the retrieval of information
from an external database. This data, concerning menu items for a cafeteria, shall be accessed
by two types of users, the cafeteria director, who sets the day’s menu from a standard list of
food items, and the cafeteria patrons, who access the day’s menu after it has been set by the
cafeteria director.
When the application is initially activated, the user is given the opportunity to enter as a
regular user or as the cafeteria director. The cafeteria director will have to enter a password
(use “director” for that purpose), but passwords are not necessary for regular users.
The cafeteria director will be expected to set the cafeteria’s lunch menu for the day, selecting
from the different food items listed in the external database. The director must choose:
Ÿ At least six different entrees
Ÿ At least four different sandwiches
Ÿ At least three different salads
Ÿ At least four different “extras” (i.e., side dishes or bread)
Ÿ At least three different desserts
Ÿ All of the beverage choices
Ÿ At least three “healthy” choices (not including beverages).
Prior to exiting the application, the director may save the specified menu, but no provision
needs to be made for editing a menu after it has been saved.
Regular cafeteria patrons using this application will be able to see the latest menu saved by
the cafeteria director, including pictures of the menu items (if available), as well as descriptions
of the menu items and their prices.

The Food database that is provided contains a single table with the definition listed in the table above. 

Keep in mind that other features might be added to this application at a later date, so make sure

that your design and implementation accommodates these potential enhancements (although you

will not implement any of them!):

· The cafeteria’s expansion to include breakfast and/or dinner menus.

· Detailed nutritional information (calories, fat, carbs, etc.) about menu items.

· Pick-up and delivery capabilities for patrons.

You are strongly encouraged to bring early versions of your design to the instructor for feedback. You

may also feel free to discuss your early design ideas with your classmates, but remember that showing

your actual code to anyone besides the instructor is considered academic misconduct and will be dealt

with as such. Also, remember to fully document your program, explaining your design as needed.

Remember that your entire project folder is due on your drop-box
