It follows a **REST-style architecture**, exposing endpoints for data management and interaction with a relational database, deployed on an **Apache Tomcat container**.\n\nEmergency Room (ER) Management System built with **SQL and E-R schema modeling**, designed to track patients, doctors, visits, examinations, prescriptions, and personal medical history. The system provides a **comprehensive backend** for hospital operations, including patient re-examinations, medication tracking, test results, and special conditions (e.g., COVID-19).  \n\nThis project highlights skills in **backend development, normalized schema design, complex SQL queries, and real-world hospital workflow modeling**.\n\n---\n\n## 📂 Features \u0026 Highlights\n\n- **Java Servlets Backend** – Handles requests and implements business logic via REST-style API endpoints.\n- **Relational Database Integration** – Uses JDBC with a normalized SQL schema to manage patients, doctors, visits, examinations, prescriptions, and medical history.\n- **E-R Diagram Design** – Models hospital ER workflow with entities, relationships, keys, and constraints.\n- **Complex SQL Queries \u0026 Analytics** – Multi-table JOINs, nested subqueries, GROUP BY + HAVING for advanced reporting (top doctors, frequent patients, COVID-19 cases), and referential integrity checks.\n- **Patient History Management** – Fetches past visits, tests, and prescribed medications, including re-examinations.\n- **Deployment** – Fully configured for Apache Tomcat.\n\n\n---\n\n## 🛠️ Setup \u0026 Run\n\n1. Import the SQL schema in your preferred relational database (MySQL/PostgreSQL).  \n2. Populate sample data using provided SQL scripts in the `/db` folder.  \n3. Connect Java backend or query via SQL client to run queries and test functionality.  \n\n---\n\n## 📊 Database Design\n\n * Entity–Relationship Diagram (E-R)  included to illustrate schema.\n * Schema  covers entities, relationships, keys, and constraints.\n * Showcases  normalization and mapping to SQL.\n\n\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fantoniakras%2Femergency-room-management","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fantoniakras%2Femergency-room-management","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fantoniakras%2Femergency-room-management/lists"}
