In this case, the attributes will be as follows: Step 2: The second step is to map out the attributes of the entities. For example, if you require to observe which patient goes to which hospital or whether they have a previous record or not, or if you simply want to analyze the number of patients a doctor treats, then your main entities will be as follows: As per your requirement, you will have some main entities. Step 1: The first step is to identify the entity sets.

These ER diagrams help them to visualize all the database tables and identify the relationships between different entities and their attributes. So, people use ER diagrams to design their hospital management systems. Furthermore, it also aids in the job completion of health care providers. A hospital management system ensures that information regarding health care is managed properly. Since hospitals are health care providers, thus they need to have efficient management. You can continue to add or delete tables, modify the existing tables, and alter table relationships until the new database diagram is complete.ER Diagram Examples for Hospital Management Systems The tables are displayed graphically in the new database diagram. Select the required tables in the Tables list and click Add. In Object Explorer, right-click the Database Diagrams folder or any diagram in that folder.Ĭhoose New Database Diagram on the shortcut menu. Additionally, you can modify indexes and constraints. Using database diagrams you can create and modify tables, columns, relationships, and keys. Database diagrams graphically show the structure of the database.
