Napier Courier

"Napier Couriers" visit customers to pickup and deliver parcels around Edinburgh. They need to maintain a list of all the visits that they make. Each visit has a customer name, customer address and arrival time. Pickups also have a delivery name and a delivery address.

• Create a class diagram showing your design. You do not need to include GUI classes (forms) at this stage.
• Implement the classes identified in your diagram using C#
• Add a GUI (using windows forms) to allow the following
  • Viewing a summary list of all pickups/deliveries
  • View a list of only pickups
  • View a list of only deliveries
  • Add a new pickup
  • Add a new delivery
  • Edit an existing pickup
  • Edit an existing delivery
  • Delete a pickup
  • Delete a delivery
• Update your class diagram to show the classes added to implement the GUI

optional : Persistence: Store the visits in a database or file so that they are loaded when the system starts.
