Employee Attendance Management System DFD Levels 0 1 2 | Dataflow Diagram Best of 2021

Employee Attendance Management System DFD – serves as a guide in creating a fully functional system. It will also help the programmers on what should be the flow of the data inside the Employee Attendance Management System through the help of diagram and symbols. This DFD for Employee attendance Management must have the Levels 0, 1 and 2.

Hi there Itsourcecoders! Today I will give you ideas about the Employee Attendance Management System DFD Diagram levels 0 1 2. This will also give you deep understanding about Employee Attendance Management System Best Data Flow Diagram (DFD) levels 0, 1 and 2 with downloadable PDF document.

Here’s what you need to know.

The Data Flow Diagram (DFD) represents the flow of data and the transformation of processes happens in Employee Attendance Management.

In the DFD, input, processing, and output are used to represent and define the overall flow of the system.

Upon reading through this article about Employee Attendance Management System you’ll then find how the system react with the user and handles data that the system is receiving.

The following are the flows that the Employee Attendance Management System can generate:

  • Manage Employee Information
  • Check Time-in and out
  • Manage Employee Leave
  • Monitor Working days and hours
  • Record Employees’ Monthly Performance

To have an advance knowledge about the Employee Attendance Management System, you must be familiarize with these symbols:

Data Flow Diagram for Employee Attendance Management System | DFD Levels 0, 1 & 2

Time needed: 10 minutes.

Here’s the Dataflow Diagram levels 0, 1 & 2 for Employee Attendance Management System and step-by-step way on how to create Employee Attendance Management System DFD.

  • Employee Attendance Management System DFD Level 0

    To start with, let us familiarize what is Employee Attendance Management System DFD level 0.

    The Employee Attendance Management System DFD level 0 is also known as context diagram. It’s shows an abstract view, with the mechanism represented as a single process with external parties.

    This DFD level 1 for the Employee Attendance Management 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 Employee Attendance Management System monitoring. This will also serve as a guide as you go through the deeper processes of the Employee Attendance Management 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.

  • Employee Attendance Management System DFD Level 1

    Next to the context diagram is the level 1 data flow diagram.

    The content of Employee Attendance Management System DFD level 1 must be single process node from the context diagram and is broken down into its sub processes.

    In this level, the system must display or reveal further processing information.

    The following are essential data to accommodate:
    • Employee Records
    • Employee Information
    • Time in Records
    • Time out Records
    • Leave Records
    • Performance Report

    These procedures require information such as record of employees, time-in and out, leave and performance reports from which served as the bases for the company admin to manage the Employee Attendance Management System. This type of data is represented by a data store.

    With being knowledgeable about the DFD level 1 of the Employee Attendance Management 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 the stated System Project.

  • Employee Attendance Management System Level 2

    After presenting the Employee Attendance Management 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 Employee Attendance Management System.
    • The Level 2 DFD for the system should represent the basic modules as well as data flow between the processes in Employee Attendance Management.
    • Since the DFD level 2 is the highest abstraction level, its Employee Attendance Management 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:
    Manage Employee Information
    Check Time-in and out
    Manage Employee Leave
    Monitor Working days and hours
    Record Employees’ Monthly Performance


    DFD level 2 let’s you know the ideas on where does the data inputs goes and inputs comes within the Employee Attendance Management 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 Employee Attendance Management System DFD levels 0, 1 and 2.

Additional Knowledge on DFD Levels 0, 1 & 2 of Employee Attendance Management System.

What is Employee Attendance Management 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.

Context diagrams (level 0 DFDs) are diagrams in which the entire system is represented as a single process.

A single process node and its connections to external entities are depicted in Level 0 data flow diagrams.

What does Employee Attendance Management System level 1 DFD entail?

Level 1 DFDs 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.

The System level 1 DFD lists all of the major sub-processes that make up the entire system. A level 1 DFD can be thought of as a “detonated view” of the context diagram.

A single production node and its relationships to external entities are depicted in Level 0 data flow diagrams. Level 1 DFDs 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.

What does Employee Attendance Management System level 2 DFD entail?

The 2-level DFD delves even deeper into the concepts of 1-level DFD. It can be used to plan or record all of the specific/necessary information about how the system works.

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

Conclusion

All in all, the ideas explained in this article were all formulated to provide you the exact details on how would you build your own data flow diagrams. It is also to make sure that the data inputs and outputs are in the right place while building the said project.

Now why should you make your data flow diagram right?
It is because, the data flow diagram serves as the blueprint of how would you secure the flow of data in the project. And through this, you will be able to build your project right and meet your requirements.

And that completes our discussion about data flow diagram! And I hope that this discussion about Employee Attendance Management System Data Flow Diagram Levels 0 1 2 | Best DFD 2021 will help you a lot.
