CHU Management System - Java Project with Design Patterns

1. Introduction

This project aims to design and implement a management system for a University Hospital Center (CHU) using design patterns in Java. The objective is to effectively model and structure CHU El Jadida, considering buildings, staff, services, patients, and sections.

2. Technologies Used

• Java EE (JEE): For developing the web-based application.
• JDBC: For managing database connections and queries.
• Relational Database: Designed to store and manage all CHU entities.

3. CHU Architecture

CHU El Jadida consists of several main entities:

• Buildings: Administration, laboratories, radiology, emergency, general medicine, medical specialties, surgery, etc.
• Staff: Director, administrators, doctors, nurses, and support staff.
• Services: Medical services, paramedical services, emergency, analysis, radiology, and technical services.
• Patients: Of all ages and types, with a unique identifier and medical status.
• Sections: Groups of over 100 patients assigned to doctors.

4. Design Patterns Used

This project implements four design patterns to ensure a robust and maintainable architecture:

a. Singleton

• Ensures a single instance of database connection to avoid redundancies and improve efficiency.

b. Factory Method

• Allows the creation of different types of buildings based on their categories.

c. Composite

• Facilitates the management of a group of hospital services as a single logical unit.

d. Mediator

• Manages interactions between department heads to coordinate CHU activities.

5. UML Diagrams

The following diagrams correspond to the implementation of the design patterns:

1. Singleton Diagram: Shows the structure and use of the single instance connection.

3. Factory Method Diagram: Describes the dynamic creation of buildings.

   

4. Composite Diagram: Demonstrates how services are grouped into a single unit.

   

5. Mediator Diagram: Explains the interactions between department heads.
