Activity Diagram for the Airline Management System

Create some activity diagrams for the airline management system.

Activity diagrams are a great way to visualize the flow of messages from one activity to the other in the system. There can be different activity diagrams that we can create for the airline management system. In this lesson, we will create activity diagrams for the following two activities:

  • Creating an itinerary

  • Activity challenge: The user receives a confirmation notification after making the payment.
