In this case study, we will design a database for a Hospital Management System. The objective is to model a system that can manage information about patients, doctors, treatments, room assignments, guardians, and medical tests. We’ll follow a structured approach, step-by-step, to create an ER diagram and map it to a relational schema.

Requirements Analysis

The first and most critical step in database modeling is understanding the requirements of the system. This involves interacting with stakeholders, analyzing existing processes, and defining the scope of the system.
