Data Flow Diagram for Passport Automation System
Data Flow Diagram for Passport Automation System this is frequently used as a preliminary step to create an overview of the application without going into great detail, which can then be elaborated. It typically consists of overall application dataflow and passport processes.
A data flow diagram (DFD) represents the information flow for any process or system. It shows data inputs, outputs, storage points, and the routes between each destination using defined symbols such as rectangles, circles, and arrows, as well as short text labels.

What is DFD for Passport Automation System
DFD for Passport Automation System is a DFD that illustrates the overall flow of data in a project. Also, it must be included in your project documentation as the foundation for project development.
The Passport Automation System serves as a link between the applicant and the authority in charge of passport issuance. It aims to improve the efficiency of passport issuance while minimizing the difficulties involved to the greatest extent possible.
The DFD (Data Flow Diagram) display the overall of flow of data inside the system. Its focus is in the movement of data that enters and exits the system.
What 0 level Data Flow Diagram for Passport Automation System
It is also referred to as a context diagram. It is intended to be a conceptual view, with the system illustrated as a single process with relationships to external entities. Moreover, it displays the entire system as a single bubble with incoming and outgoing arrows indicating input and output data.
Context diagram (0 level DFD) represents the system’s general process with external entities into single node. And then, it shows the overall structure with labeled arrows indicating the input and output data. In addition, its illustration shows the main process (represented by a box), the external entities and the data flow inside the system.
What Data Flow Diagram for Passport Automation System level 1 and 2
First Level DFD (1st Level) shows how the system is divided into sub-systems (processes), each of which deals with one or more data flows to or from an external agent, and which together provide all of the system functionality.
In a 1-level DFD, the context diagram is broken down into many bubbles or processes. Meanwhile, in this level, we show you how the system works and break down the high-level process of 0-level DFD into smaller parts.
The single process node from the context diagram is divided into sub processes in a level 1 data flow diagram. Besides, as more processes are added, the diagram will require more data flows and data stores to connect them.
The DFD Level 2 represent the database or data storage used to secure all the data that moves inside the System. Further, after presenting the DFD levels 0 and 1, next to that is level 2. Considered as the highest abstraction level, DFD Level 2 is the detailed version of DFD level 1.
A level 2 DFD describes each of the major sub-processes that comprise the entire system. Similarly, a level 2 DFD can be thought of as a “exploded view” of the context diagram. Meanwhile, it basic system modules and data flow among various modules Level 2 DFD also mentions fundamental processes and information sources.
DFD level 2 informs you about where the data inputs go and where the data inputs come within the system. Importantly, considering the dataflow levels mentioned above, you can see how important it is to break down the processes in a more specific manner.
Why Data Flow Diagram for Passport Automation System Level 0, 1 and 2 is Important?
The most importance function of Data Flow Diagram for Passport Automation System it helps the audience in understanding what is happening in the application. Also how the system manages its data at different levels of detail.
The Data Flow Diagram Levels importance has their roles in emphasizing the DFD of passport automation system. Furthermore, the Level 0 or Context Diagram presents the single and main process of System as well as the main users and the data, whereas the Data Flow Diagram Level 1 and 2 portrays specific process and sub processes and the detailed movement of data.
Conclusion:
It is very important for you to know the diagrams that used to design and build the Data Flow Diagram for Passport Automation 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,
