🏥 Hospital Management System (HMS)
Enterprise-grade role-based hospital management system for streamlined clinical, administrative, and operational workflows.
📌 Problem Statement
Hospitals require centralized control over patient records, doctor management, department administration, appointment scheduling, prescriptions, and audit tracking.
Manual or disconnected systems introduce inefficiencies, security risks, and poor traceability.
This system provides a structured, secure, database-driven platform to manage multi-role healthcare operations in a unified environment.
