Face Mask Detection DFD (Data Flow Diagram) Levels 0, 1, and 2

The Face Mask Detection System DFD is a diagram used to show the overall data management of the project. It has 3 main levels that shows the Face Mask Detection System data handling which is the DFD Level 0, 1, and 2. These DFD levels illustrates the Face Mask Detection data management concept from the basics up to specific details.

Here’s what you need to know.

The Data Flow Diagram (DFD) represents the flow of data and the transformations in Face Mask Detection. In the DFD, input, processing, and output are used to represent and define the overall system.

Upon reading through this article about Face Mask Detection System you’ll then find how the system react with the user and handles data that the device or camera recognizes.

The following are the data involved in Face Mask Detection System DFD:

  • Face Mask Detection Information
  • Records of Person with Face Mask
  • Records of Person without Face Mask
  • Secure Real-Time Records
  • Count of Violators in Real Time
  • Count of Non-Violators in Real Time

To have an advance knowledge about the Face Mask Detection System, you must be familiarize with these symbols:

Here’s the Face Mask Detection System DFD (Data Flow Diagram) with complete explanation of its level 0, 1 and 2

  • Face Mask Detection System DFD Level 0

    The Face Mask Detection system DFD level 0 serves as an abstract view of the systems overall data handling. It is represented by a single node revealing the main process, external entities (users) and data (inputs and outputs). This level depicts the overall structure as a single bubble and comes with incoming/outgoing indicators showing input and output data.


    The context diagram illustration shows the general process done in the system. This illustration will guide you as you go through the deeper processes of the face mask detection system data flow diagrams. The design will have its supporting details in DFD Level 1 and will reveal more information about the Face Mask Detection System Data Flow Diagram.

  • Face Mask Detection System DFD Level 1

    Next to the Face Mask Detection System context diagram is the data flow diagram Level 1. Its content is derived from the previous level to expand the idea of Face Mask Detection System main process. In DFD level 1, the diagram also reveals further processing information.

    The illustration gives you the included data in completing the whole process of Face Mask Detection System. This is to determine what are the needed data and in what process would they be used. These processes shown in the Data Flow Diagram were all based on the concept of Face Mask Detection System.

    Being knowledgeable about the DFD level 1 of the Face Mask Detection 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 Face Mask Detection system. Then you will be also informed about the outputs that the system gives.

  • Face Mask Detection System Level 2

    After presenting the Face Mask Detection System DFD 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 Face Mask Detection 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 Face Mask Detection 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.

    The Processes that the system should prioritize are as follows:
    • Setting Face Mask Detection
    • Records of Person with Face Mask
    • Records of Person with Face Mask
    • Secure Real-Time Records
    • Count of Violators in Real Time
    • Count of Non-Violators in Real Time

    DFD level 2 let’s you know the ideas on where does the data inputs goes and inputs comes within the Face Mask Detection System. Considering the the dataflow 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 DFD will also be your references as you make and design your own project DFD levels 0, 1 and 2.

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. Considering the the data flow diagram levels mentioned above, you can determine well the importance of breaking the processes into more specific manner.

Additional Knowledge on DFD Levels 0 1 2 of Face Mask Detection System 2021

Face Mask Detection System DFD level 0

The University Management System DFD level 0 is also known as context diagram. 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. Context diagrams (level 0) are diagrams in which the entire system is represented as a single process.

Face Mask Detection System DFD level 1

Online Shopping System DFD Level 1 provides a broad overview and greater depth of the context diagram. This means that the single process node from the context diagram is broken down into its sub-processes in level 1 data flow diagram.

DFD level 1 lists all of the major sub-processes that make up the entire system and is thought of as a “detonated view” of the context diagram. That is because the DFD Level 1 reveals the included processes that completes the system’s function.

Face Mask Detection System DFD level 2

The DFD Level 2 goes 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. It is the DFD’s highest abstraction level and represents the system’s basic modules as well as data flow between them.
