This repository contains Phase 1 of the Preze Cinemas Desktop project, developed for the Software Engineering course.
The goal of the project is to design a cinema ticket reservation system that enables customers to browse movies, reserve tickets, and complete secure payments while allowing cinema operators to manage screenings and availability.
Phase 1 focuses on system analysis and requirements modeling through Use Case Diagrams.

Project overview |
The application supports cinema customers in:
- Browsing available movies
- Selecting showtimes and screening rooms
- Reserving seats and tickets
- Completing secure payments
- Receiving digital ticket confirmations
This phase defines how users interact with the system, forming the basis for future implementation phases.
The first development phase identifies:
- System actors
- System services
- User interaction flows
- External system interactions
All interactions are modeled using UML Use Case diagrams.
Represents all end users of the system:
- New customers registering accounts
- Existing customers logging in
- Customers booking movie tickets
An external system responsible for:
- Payment validation
- Account balance verification
- Transaction confirmation
Customers can:
- Register with personal information
- Log in securely using credentials
- Manage access to reservations
Users are able to:
- Select movies
- Choose available showtimes
- Select rooms and available seats
- Reserve tickets for screenings
Enhanced viewing options may include:
- Dolby Atmos sound
- 3D movie projection
Payments are processed through the external Bank System, including:
- Balance validation
- Transaction approval or rejection
After successful booking, users may:
- Obtain proof of transaction
- Download or store digital tickets
The use case model applies UML relationships to organize behavior.
Mandatory sub-processes, such as:
- Login including credential verification.
Conditional processes, such as:
- Displaying error messages
- Applying promotional discounts
- Handling exceptional scenarios
Phase 1 establishes the functional interaction model of Preze Cinemas Desktop, serving as the foundation for future design and implementation phases. The system aims to provide a user-friendly cinema reservation experience while ensuring secure transaction handling and structured reservation management.
