Step 5: The last step is to combine all the relationships and draw a complete ER diagram. Since a single patient has multiple medical records, thus it is a one-to-many relationship. Since a doctor is associated with many patients, it is a one-to-many relationship.

Step 4: Once you have identified all the relationships, it is time to map out the lines. Based on the cardinalities, you have to place the appropriate sign. This can be done by identifying primary and foreign keys.įor example, if the hospital table makes a foreign key reference to the patient ID of the patient table, then both of them will be joined together. Step 3: Identify the type of relationship that exists between the entities. For the above example, they will be hospital ID, patients ID, record ID, and doctor ID. Medical Record: Record ID, problem, date of examination, and patient ID.ĭoctor: Doctor ID, name, qualification, salary, and hospital ID.

Step 1: The first step is to identify the entity sets. The main objectives of the system is which shows and help us to collect most of the. A Project of Hospital Management includes registration of patient storing their details into the system and also computerized billing in the pharmacy, and test labs. Since ERDs are of great use for designing a hospital management system, here we are going to walk you through the steps of designing an ER diagram for your hospital management system.
