Create a context diagram DFD Level 0 for the following high-level requirements in a housing system
run by the Campus Housing Service. The Campus Housing Service helps student find apartments.
Owners of apartments fill in information forms about the rental units they have available (e.g.,
location, number of bedrooms, monthly rent), which are entered into a database.
Students can search through this database via the web to find apartments that meet their
needs (e.g., a two-bedroom apartment for $800 or less per month within half a mile of
campus).
They then contact the apartment owners directly to see the apartment and possibly rent it.
Apartment owners call the service to delete their listing when they have rented their
apartment(s).
Wow Pizza wants to install a system to record orders for pizza and chicken wings. When regular
customers call Wow Pizza on the phone, they are asked their phone number. When the number
is typed into a computer, the name, address, and last order date is automatically brought up on
the screen. Once the order is taken, the total, including tax and delivery, is calculated. Then the
order is given to the cook. A receipt is printed. Occasionally, special offers (coupons) are printed
so the customer can get a discount. Drivers who make deliveries give customers a copy of the
receipt and a coupon (if any). Weekly totals are kept for comparison with last year's performance.
