Learning Outcomes

Through this project, I strengthened my understanding of:

• Object-Oriented Programming (OOP) principles in Java.
• Designing classes and managing relationships between objects.
• File handling for persistent data storage.
• Organizing Java projects into models and services.
• Building a complete console-based management system.

Future Improvements

• Migrate the current console-based application to Spring Boot.
• Develop RESTful APIs for managing patients, doctors, and appointments.
• Replace text file storage with a relational database such as MySQL.
• Use Spring Data JPA for database operations.
• Add authentication and role-based access for different users.
• Develop a web-based user interface for the system.
