Usability: Intuitive design with WPF styling and MVVM architecture.

Reliability: Consistent data updates and minimal downtime.

---

5. User Roles

Customer: Users booking flights and managing their bookings.

Admin: Airline personnel managing flights, pricing, and seat availability.

---

6. WPF-Specific Features

UI/UX:

Use WPF styles, templates, and data binding for a modern and responsive UI.

Create a seat map using WPF canvas or grid control with interactive seat icons.

Leverage animations for better user feedback (e.g., seat selection, loading indicators).

MVVM Pattern:

Separate logic from UI for scalability and maintainability.

Implement commands and observable collections for data binding.

Localization:

Add support for multiple languages using WPF resources.

Printing and Export:

Use WPF printing APIs to print or export tickets and reports.

---

7. Technology Stack

Frontend: WPF with MVVM architecture.

Backend:

ASP.NET Core (or other APIs) for flight and booking data.

SQLite, SQL Server, or MySQL for the database.

Libraries/Tools:

MahApps.Metro for enhanced UI/UX.

Prism or MVVM Light for MVVM implementation.

DevExpress or Telerik for advanced controls (optional).

Payment Gateway: Integrate with Razorpay, PayPal, or Stripe.

Notifications: Use email APIs (e.g., SendGrid) for updates.

---

8. Constraints

Ensure the seat map updates in real-time when multiple users access the same flight.

Maintain high accuracy in booking confirmations to prevent double bookings.

Optimize performance for handling large datasets of flights and bookings.

---

9. Additional Considerations

Offline Mode: Allow users to access booked tickets or search flights offline with locally cached data.

Data Backup: Ensure regular backups of booking data for reliability.

Accessibility: Provide options like keyboard navigation and high-contrast themes for accessibility.
