Phase IV – Prototype & Testing

This phase details the implementation, demonstration, and evaluation of the Sillah (صلة) Family Health Management System prototype. It validates how the design and requirements from previous phases were successfully transformed into a working Java application following software engineering best practices.

---

4.1 Prototype Overview

The Sillah system prototype was developed using Java (JDK 17) and demonstrates the use of Object-Oriented Programming (OOP) principles including encapsulation, inheritance, and modularity. It allows users to register, add family members, book appointments, receive health alerts, and view awareness content — all within a Command-Line Interface (CLI) environment.

Development Environment: Visual Studio Code / IntelliJ IDEA
Programming Language: Java 17
Paradigm: Object-Oriented Programming
Testing Types: Unit Testing and Integration Testing

This prototype represents a complete, testable version of the system design presented in Phase III and serves as the foundation for future GUI or web expansion.

4.2 Implemented Modules

Module	Description
Main.java	Acts as the program entry point and manages the main menu navigation.
User.java	Handles user registration, login, and authentication.
FamilyMember.java	Stores and manages individual family members’ information.
Appointment.java	Manages booking, modification, and cancellation of appointments.
Clinic.java	Stores clinic data, working hours, and appointment slots.
HealthEvent.java	Records checkups and medical events such as ECG results.
BookingSystem.java	Connects user, clinic, and appointment modules for booking coordination.
AlertSystem.java	Automatically generates reminders and alerts for upcoming events.
AwarenessHub.java	Provides verified educational health content to users.
Message.java	Supports communication between users and clinics.

Each class was independently implemented, compiled, and verified to ensure that all functional requirements were met.

4.3 Console Interaction Example

The prototype uses a menu-driven console interface where users interact with the system by selecting options.
