Running the Application with Eclipse

1. Download or clone the repository.
2. Open Eclipse.
3. Select File → Import.
4. Select General → Existing Projects into Workspace.
5. Choose the project directory.
6. Make sure the libraries from the lib directory are included in the project build path.
7. Clean the project using Project → Clean.

The database file must remain in the root directory of the project so that the application can access it correctly.

The repository contains demonstration data only.

Possible Future Improvements

• Convert the project to Maven
• Replace Microsoft Access with PostgreSQL or MySQL
• Improve input validation
• Add a modern user interface
• Add contact export and import
• Add unit tests
• Implement password-protected access
