The DFD for Doctor Appointment System is the overall flow of data on the project. It is used to document the transformation of data (input-output) for project development.
This doctor appointment system DFD consists of DFD levels 0, 1, and 2. It also uses entities, processes, and data to define the whole system.
What is Doctor Appointment System DFD?
The DFD (data flow diagram) is a method which use for doctor appointment system development. It represents the system major processes and alternatives that generate the internal flow of project management.
Additionally, the data stores properly in categorized to illustrate the doctor appointment system structure. Take note that DFD is not part of the Doctor Appointment, but they complement each other in explaining the project activities, behaviors, interactions, and structure.

Importance of Data Flow Diagram (DFD)
The importance of the data flow diagram for doctor appointment system is to show the developers the actual happenings in the system. This is done by visualizing the system’s data management at various levels.
Doctor Appointment System Data Flow Diagram
A thorough explanation is provided for the example data flow diagram for doctor appointment system. This example emphasizes the three DFD levels (DFD Levels 0, 1, and 2).
0 Level DFD for Doctor Appointment System
The context diagram is an alternative name for the Level 0 Data flow Diagram for Doctor Appointment System. Users, the main process, and data flow make up its parts. Also, the project concept is demonstrated using the single process visualization.
DFD Level 0 shows the entities that interact with a system and defines the border between the system and its environment. This diagram also depicts the doctor appointment system at a high level.
The illustration presents the main process in a single node to introduce the project context. This context explains how the project works in just one look. The user feeds data into the system and then receives the output from it.
Level 1 DFD for Doctor Appointment System
The “detonated view” of the context diagram is Doctor Appointment System Data flow diagram Level 1. Its function is to deepen the concept derive from the context diagram.
Specifically, level 1 shows the broader details of Doctor Appointment System Level 0. This is to clarify the paths (flow) of data and its transformation from input to output.
The designed diagram portrays four different scenarios: customer information management, appointment records management, appointment status monitoring, and transactions management.
DFD Level 2 for Doctor Appointment System
Level 2 Data flow diagram for Doctor Appointment System is also the highest abstraction of the data flow diagram. This level also broadens the idea from the DFD level 1. It includes the sub-processes from level 1 as well as the data that flows.
However, not all of the processes in the project must have sub-processes. Only provide this diagram if needed. As long as your previous diagrams were clear and precise, this level is not required.

Data Flow Diagram Notations:
To define the data flow diagram, we used DFD notations. They were presented in symbols to be understood easily. The symbols present the following:
These data flow diagram notations represent the total data handling. Using these Data Flow Diagram symbols would also help to draw attention to the system’s architecture in a simpler way.
In conclusion, we have discussed the things that we need to know to create a data flow diagram. Its main purpose is to emphasize the transformation of data from input to output. Along with this, DFD levels were very useful in elaborating the system.
