PatientCarePlus

A Java Swing desktop application for hospital patient-care management — patient registration, medical records, diagnoses, prescriptions, monitoring data, lab requests, billing and insurance claims — built on a layered boundary / controller / entity architecture over an Apache Derby database.

Software engineering course project.

Architecture

src/
├── boundary/           Swing screens (NetBeans GUI Builder: .form + .java)
├── controller/         AuthController, PatientCareController — app logic + JDBC
├── entity/             domain model
├── db/                 DatabaseManager — connection handling
├── enums/              Role, AdmissionStatus, BillingStatus, ClaimStatus
└── patientcareplus/    Main.java — entry point

Each layer only talks downward: boundary → controller → entity / db.

Entities

User · Patient · Doctor · Nurse · HospitalAdmin · MedicalRecord · MonitoringData · LabRequest · Billing · InsuranceClaim

Enums

Role (DOCTOR, NURSE, ADMIN) · AdmissionStatus · BillingStatus · ClaimStatus (all PENDING / PAID / REJECTED) · ClaimStatus (SUBMITTED / APPROVED / REJECTED)

Database

Apache Derby, reached through the Derby Network Client:

jdbc:derby://localhost:1527/pcplusdb;create=true

The app expects a Derby Network Server listening on 127.0.0.1:1527 — an embedded connection will not work as-is.

Schema is created automatically on first run:

APP_USERS · PATIENT · PATIENT_INSURANCE · MEDICAL_RECORD · DIAGNOSIS · LAB_RESULT · PATIENT_MONITORING

---

Demo credentials

Seeded automatically on first run, for local development only:

Role	Email	Password
Admin	admin@test.com	1234
Doctor	doctor@test.com	1234
Nurse	nurse@test.com	1234
Receptionist	reception@test.com	1234

Requirements

• JDK 25 — the NetBeans project sets javac.source=25 / javac.target=25
• Apache Derby Network Server — the client jars ship in libs/
• NetBeans (Ant project), or any IDE that understands the Ant build

Verified with JDK 25.0.4 against Apache Derby 10.17.1.0: schema creation, all four seeded logins, and patient registration all pass end to end.

Running

1. Start the Derby Network Server on port 1527.
2. Make sure libs/derbyclient.jar and libs/derbyshared.jar are on the project classpath — already declared in nbproject/project.properties.
3. Build and run. Main class: patientcareplus.Main

The schema and demo users are created on the first launch, so no manual SQL is required.

Notes

• Passwords are stored and compared in plaintext. That is fine for a local coursework project but would need hashing before this was ever used for anything real.
• libs/ contains the Derby client jars, committed so the project builds without a dependency manager.
