Development Notes

This system was developed as an educational project to demonstrate:

• Object-oriented programming principles
• Console-based application development
• CRUD operations implementation
• Input validation techniques
• Clean code organization and separation of concerns

The code includes Filipino language comments (like "Gumawa ng bagong person") showing the developer's origin while maintaining English method names and UI text for international accessibility.

Future Enhancements

1. Add search functionality
2. Implement data persistence (file storage)
3. Add sorting capabilities
4. Include more student fields (email, contact number)
5. Implement user authentication
6. Add reporting features
