Activity Diagram for the Movie Ticket Booking System

An activity diagram is 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 our movie ticket booking system. In this lesson, we will create activity diagrams for the following two activities:

• The customer makes a booking for the movie.

• Activity challenge: The admin cancels a show.

The customer makes a booking for the movie#

The following are the states and actions that will be involved in this activity diagram.

States#

Initial state: The customer opens a search for a movie.

Final state: The customer receives a ticket for the movie.

Actions#

The customer searches for a movie by specific criteria and selects their movie. The customer then selects their required seat and pays according to their seat type. The payment is carried out either through cash or a credit card. After successful payment, the customer receives the movie ticket.

Based on the order above, the activity diagram of a customer making a booking for the movie is given below.

Note: Here we assume that the customer is purchasing a single cinema seat.

Activity challenge: Admin cancels a show#

You will create an activity diagram of an admin canceling a show for a movie.

A skeleton of the activity diagram is given below.

Notice that the actions in the diagram above are numbered from 1 to 8. The slots shown below represent the activities and the arrows represent the flow from one activity to the other.

Can you rearrange the given slots in the correct order they should appear in the activity diagram above?

We've looked at some of the activity diagrams of our movie ticket booking system. In the next lesson, we will present the code for our designed classes in some of the most popular languages.
