Barangay Information System DFD Levels 0, 1, and 2
The Barangay Information System DFD is a diagram used to show the overall data management of the project. It has 3 main levels that shows the Barangay Information System data handling which is the DFD Level 0, 1, and 2. These DFD levels illustrates the Barangay Information data management concept from the basics up to specific details.
The DFD Level 0, 1 and 2 has their part in explaining the data handling of Barangay Information System. The DFD Level 0 (context Diagram) shows the overall function of Barangay Information System in a single process. It also serves as the main basis as you make the proceeding Levels. DFD Level 1 broadens that DFD Level 0 and the DFD Level 2 includes the databases of the all the data that will be part of the Project’s main function.
Here’s what you need to know.
The Data Flow Diagram (DFD) represents the flow of data and the transformations in Barangay Information System. These transformations occurs as data enters and exits a system. In the DFD, input, processing, and output are used to represent and define the overall system.
The following are the data that are present in Barangay Information System DFD:
- Barangay Information
- Residents’ Information
- Barangay Health Records
- Residence Qualification
- Barangay Certifications

Time needed: 10 minutes.
Here’s the Data Flow Diagram for Barangay Information System which explains the overall flow of data throughout the software in form of DFD levels 0, 1, and 2.
- Barangay Information System DFD Level 0
To start with, let us familiarize what is Barangay Information system level 0.
The Barangay Information system level 0 is also known as context diagram. It’s supposed to be an abstract view, with the mechanism represented as a single process with external parties.
This DFD for the Barangay Information system depicts the overall structure as a single bubble. It comes with incoming/outgoing indicators showing input and output data.
In this data flow diagram you will see the general process done in barangay information monitoring. This will also serve as a guide as you go through the deeper processes of the Barangay Information system data flow diagrams.
As you see, when you build the levels of data flow diagrams, the connections of the transactions and data also broadens and gets more specific.
- Barangay Information System DFD Level 1
Next to the context diagram is the level 1 data flow diagram.
The content of Barangay Information System DFD level 1 must be single process node from the context diagram and is broken down into sub processes.
In this level, the system must display or reveal further processing information.
These procedures require information such as record of residents, health, certifications and barangay files from which served as the bases for residents and barangay admin to manage the Barangay Information system. This type of data is represented by a data store.
With being knowledgeable about the DFD level 1 of the Barangay Information System, you will know then its broaden context terms.
In addition to that, this may also serve as your reference on how the inputs or data fed on the system. Then you will be also informed about the outputs that the system gives.
These processes shown in the DFD were all based on the concept of Barangay Information System.
- Barangay Information System DFD Level 2
After presenting the Barangay Information system Data Flow Diagram levels 0 and 1, next to that is level 2.
Here’s what you need to consider in creating data flow diagram level 2 for Barangay Information system.
• The Level 2 DFD for the system should represent the basic modules as well as data flow between them.
• Since the DFD level 2 is the highest abstraction level, its Barangay Information system processes must be detailed that is based on the DFD level 1.
Finally, after figuring the processes given in the system, the user will now have their request being processed.
DFD level 2 let’s you know the ideas on where does the data inputs goes and inputs comes within the Barangay Information System. Considering the the data flow levels mentioned above, you can determine well the importance of breaking the processes into more specific manner.
The presented level not only shows you the detailed processes of system, but also gives you precise destination of the data that flows in the system.
This diagram will also be your references as you make and design your own project DFD levels 0, 1 and 2.
Additional Knowledge on Barangay Information System DFD Levels 0, 1, and 2
Barangay Information System DFD level 0
A context diagram is another name for it. With the mechanism represented as a single process and external parties it will be an abstract view. It depicts the overall structure as a single bubble with incoming/outgoing indicators showing input and output data.
The data flow diagram level 0 also considers the entire system to be a single process and emphasizes the system’s interaction with external entities.
Barangay Information System DFD level 1
DFD Level 1 provide a broad overview but go into greater depth than a context diagram. The single process node from the context diagram is broken down into sub processes in a level 1 data flow diagram. DFD Level 1 provide a broad overview but go into greater depth than a context diagram.
The System DFD level 1 lists all of the major sub-processes that make up the entire system. DFD level 1 is thought to the “detonated view” of the context diagram.
Barangay Information System DFD level 2
The DFD level 2 delves even deeper into the concepts of DFD level 1. It can be used to plan or record all of the specific/necessary information about how the system works.
DFD Level 2 is the DFD’s highest abstraction level and represents the system’s basic modules as well as data flow between them.
So that completes our discussion fellas! And I hope that discussion about Barangay Information System Data Flow Diagram Levels 0, 1, and 2 will help you a lot.
Now let me ask you something. What have you learned through the discussion?
