An Entity-Relationship (ER) diagram is a visual representation of the data structure of a database. It is used to design and plan the database structure for a hospital management system. ER diagrams help to visualize all the database tables and identify the relationships between different entities and their attributes .
There are several steps involved in designing an ER diagram for a hospital management system. The first step is to identify the entity sets, which include patients, doctors, tests, and other relevant entities . Once the entity sets have been identified, the next step is to define the relationships between them. For example, a patient can have many tests, but each test belongs to only one patient .
