Use Case Diagram for the Movie Ticket Booking System

Let’s build the use case diagram for the Movie Ticket Booking system and understand the relationship between its main actors and functions. First, we’ll define the different elements of our system, followed by the complete use case diagram.

System

Our system is the Movie Ticket Booking system. It manages movie and show listings, ticket bookings, seat reservations, and notification delivery.

Actors

Now, we will define the main actors of our movie ticket booking system.

Primary actors

• Customer: Searches for movies, creates bookings, reserves seats, pays for tickets, views/modifies/cancels bookings.

• Ticket agent: The ticket agent will assist the customer and perform almost all the tasks that a customer can do, such as creating a booking of the movie ticket on behalf of the customer, searching for movies, and reserving seats at the halls, except for modifying and canceling a booking.

Secondary actors

• Admin: Manages movies and showtimes by adding, deleting, or updating them.

Use cases

In this section, we will define the use cases for movie ticket booking systems. We have listed the use cases according to their respective interactions with a particular actor.

Note: Some use cases will occur multiple times because they are shared among different actors in the system.

Admin

• Add show: To add a new show for a particular movie in any cinema hall, specifying the movie, time, hall, and seat layout.

• Modify show: This function allows you to update the details of an existing show (such as date, time, or hall assignment) for any movie.

• Delete (cancel) show: To remove or cancel a scheduled show for a movie. This may also trigger notifications to affected customers.

• Add movie: To add a new movie to the system’s listing, specify the title, language, genre, release date, and description.

• Update movie: This is to edit the details of an existing movie, such as title, language, genre, or duration.

Relationships

This section describes the relationships between actors and use cases in the Movie Ticket Booking system. Understanding these relationships clarifies how different system components interact and helps ensure a robust, consistent design.

Generalization

Generalization shows inheritance or specialization between actors or use cases. The Search movie use case generalizes more specific search types:

• “Search movie by title”

• “Search movie by language”

• “Search movie by genre”

• “Search movie by release date”

Each specialized search is a specific way to perform the generic Search movie action. By showing generalization, we communicate that users can choose any of these criteria without changing the main workflow, and future new criteria can be added without restructuring the diagram.

Associations
