Hospital Management System DFD (Data flow diagram) is often used as a first step to get a general picture of the system without going into too much detail, which can later be expanded on.
In most cases, this is the overall data flow and processes of the Hospital process that are in the application.
The Hospital Management System’s Data Flow Diagram is made up of data, external entities, data storage where information is kept, and processes.
It uses symbols to show how the data flows together.

What is DFD for Hospital Management System
The Data Flow Diagram (DFD) for Hospital Management System – one of the methods used for development.
It represents the system’s major processes and alternatives that generate the flow of data within the system. Moreover, the data included in the Data Flow Diagram is labeled properly to guide the developers on the structure of the Hospital Management System.
Importance of DFD for Hospital Management System
The importance of DFD for the Hospital Management System is that it aids the audience in understanding what is happening in the system.
The system manages its data at different levels of detail.
The Hospital management system data flow diagram involves major levels to elaborate the flow of data within the project.
Moreover, these levels have their part in expounding the details of the system’s data flow structure. This structure will be the guide of developers in designing the system’s data handling.
The data flow diagram displays the data flow in the Hospital Management System. After that, it describes the stages required in transporting data from input to file storage and report output in a medical system.
How to Create a Hospital Management System in DFD level 0 1 2
Time needed: 5 minutes
Here’s the step-by-step way to create How to Create Hospital Management System DFD level 0 1 2.
- Example Data Flow Diagram Context Level dfd for Hospital Management System
The hospital management system DFD level 0 is also known as context diagram.
It is an abstract view with the mechanism represented as a single node process with external parties.
The overall structure is shown as a single bubble in this DFD Level 1 for Hospital Management system. It includes incoming/outgoing indicators that display input and output data.
Therefore, its illustration serves as the foundation for the next two primary levels, since it shows more specific data handling data.
- Example Data Flow Diagram Level 1
Next to the context diagram is the level 1 data flow diagram. The content of the Hospital management system Data Flow Diagram Level 1 is related to the process shown in the context diagram.
The main process will be broken down into more specific processes to deal with the data fed on the system.
Knowing the DFD level 1 of the System will allow you to understand its broader context terms.
Furthermore, this may act as a reference for how the system system manages the inputs or data provided to it.
The system’s outputs will then be communicated to you.
- Example Data Flow Diagram Level 2 for Hospital Management System
After presenting the Hospital management system DFD levels 0 and 1, next to that is level 2.
The DFD Level 2 for the Hospital Management system represents the specific destination of essential data that will complete the service of the hospital personnel.
Furthermore, Data Flow Diagram level 2 is the highest abstraction level of Hospital management system processes and they must be detailed which is based on the DFD level 1.
What is the Hospital Management System in DFD levels 0, 1, and 2?
Context diagrams (DFD level 0 ) are diagrams in which the entire system is represented in a single process. So, a single process node and its connections to external entities are depicted in this level.
Hospital Management System Level 0 or context diagram shows you the main users of the application as well as the main data that is expected to be handled by the system.
This level also gives the following levels the basis on how to broaden the idea given.
1st level DFD for Hospital Management System is an idea called a context diagram is used to give an overview and go into more depth.
So, the single process node from the context diagram is broken down into sub-processes that make up level 1.
The System DFD level 1 lists all of the major sub-processes that make up the entire system. Also, it is considered as the “detonated view” of the context diagram.
It reveals the specific processes derived from the DFD Level 0. Moreover, it adds the data included with their indicated flow inside the system.
The level 2 DFD goes even deeper into the level 1 DFD’s ideas. Using it, you can plan how the system works and record everything that is important about it.
DFD Level 2 is the most abstract level, representing the system’s basic modules as well as the data flow between them.
Level 2 displays the database used to store the system’s data inputs and the source of its outputs. You can also see here the subprocesses of the process that are shown in level 1.
Conclusion:
It is very important for you to know the diagrams that are used to design and build the Hospital Management System.
That is to help you build a fully-functioning system with the help of DFD so that you can use it.
Creating a DFD will help you see what inputs and outputs the system needs to process and transform. Not only that, but you can also connect its diagram to other diagrams, too.
