Complete CRUD operations for all tables (Passenger, Rides, Payment, Driver) 2. Oracle database integration with proper connection string 3. Backup functionality (export/import) for all tables in JSON format 4. Realistic UI with: - Header with logo and system name - Navigation tabs - Clean, responsive design - Footer 5. Data validation and error handling 6. Proper foreign key relationships maintained 7. Dropdown population for related tables To use this system: 1. Make sure you have Oracle.ManagedDataAccess NuGet package installed 2. Update the connection string with your actual password 3. Replace the logo.png with your actual logo file 4. The system will automatically handle all database operations and maintain data integrity
