Activity Diagram 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.

Create an itinerary

The states and actions that will be involved in this activity diagram are provided below.

States

Initial state: The customer chooses an option to create the itinerary.

Final state: A customer books their ticket.

Actions

The customer selects an option to create an itinerary online themselves or through the front desk officer. The customer then selects their flights. Finally, the customer books their ticket.
