The DFD (Data Flow Diagram) of a hospital system is a diagram that shows how a hospital system works. It is the layout of where a patient first starts and how they move through the system to the administration and throughout the building.

Hospitals have to store a lot of data, like data about patients, staff, supplies, appointments, surgery, medication etc. To maintain and process all of this data and provide the information they need to run the hospital it is essential that they have databases.

An ER diagram is an "Entity Relationship" diagram, which illustrates the relationships between the entities in a data model. A data model for a timetable management system might have entities like Days, Periods and Rooms. Its ER Diagram would then show that a Day is broken down into multiple Periods, and each Room might be used for multiple Periods.
This is the diagram that shows where everything is going. You will need to make one up for your business to ensure accuracy.
For any data flow diagram first look at the existing processes. Student registration, class selection, professor/teacher class assignment, testing, grading and I am sure the list goes on. Once you have provided the beginning scope of the software by pruning the list of existing processes you can then develop a list of documents and communications that are used to transfer information and authority to others in the system. It is these documents and activities that are data flow items. The entities that are involved in sending or receiving these same communications are nodes in the system. Of course this is cursory and very general answer.
