Java Hospital Management System (Swing)

This project implements a hospital management desktop application using Java Swing for the UI and JDBC for database connectivity to MySQL. Staff can register new patients, schedule appointments with doctors, and generate consultation/billing receipts.

The application follows a layered architecture with separate DAO classes for Patients, Doctors, and Appointments, keeping SQL queries out of the Swing controller classes. Input validation ensures fields like contact number and date of birth are correctly formatted before insertion.

A doctor-availability calendar (built with a JTable) helps front-desk staff avoid double-booking appointment slots, and the system prints a simple text-based receipt using Java's printing API.

Detailed Project Description

Java Hospital Management System (Swing) digitises the day-to-day records and workflows of an organisation so data is stored once, retrieved instantly and reported accurately.

How It Works
1. Role-based login separates admin, staff and end users.
2. Each module (records, bookings, transactions, reports) provides full CRUD operations with validation.
3. Data lives in a relational database with proper relationships between entities.
4. Reports and search views summarise the stored information.

Technology Roles
- Java
- Swing
- JDBC
- MySQL

Implementation Steps
1. Define requirements and draw the ER / class diagram and screen flow.
2. Set up the environment (JDK, NetBeans/Swing, MySQL Connector/J) and create the project skeleton.
3. Design the database schema / data model and seed it with sample data.
4. Implement the core modules with validation and role-based access where needed.
5. Build the user interface and connect it to the backend / data layer.
6. Test each module (unit + manual), fix edge cases and secure inputs (SQL injection, XSS, auth).
7. Prepare documentation, screenshots and a demo build.

Key Features
- Role-based access
- CRUD modules
- Search and filters
- Reports / export
- Validation and error handling

Expected Output
On completion the student will have a multi-user application with organised records and printable/exportable reports.

Deliverables
- Complete source code with comments
