Employee Management System DFD | Data Flow Diagram

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

Employee Management System DFD – serves as a guide in creating a fully functional system. That is because the dfd or dataflow diagram illustrates the flow of data within the employee management system. The illustrations gets more clearer with the use of this DFD levels 0, 1 and 2.

Good day Itsourcecoders! Now I will be giving you ideas about the Employee Management System DFD Diagram and its levels 0, 1 and 2. This discussion will not only give you deep understanding about Employee Management System Data Flow Diagram (DFD) and levels 0, 1 and 2 but also a 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 Management. And in the DFD, input, processing, and output are used to represent and define the overall flow of the system. Upon reading through this article, 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 and processes that the Employee 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 Management System, you must be familiarize with these symbols:

Data Flow Diagram for Employee Management System and its DFD Levels 0, 1 & 2

Time needed: 10 minutes.

Now here’s the Dataflow Diagram levels 0, 1 & 2 for Employee Management System and the explanation of each levels.

  • Employee Management System DFD Level 0

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

    The Employee Management System DFD level 0 is also known as context diagram. It’s shows an abstract view of main processes included in Employee managing.

    This DFD level 0 illustration of the Employee Management System depicts the overall structure as a single bubble. Then it will be explain the processes as the dfd levels gets more specific. It also comes with incoming/outgoing indicators showing input and output data.

    In this data flow diagram you will see the general process done in Employee Management System . It will serve as a guide as you go through the deeper processes of the Employee 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 Management System DFD Level 1

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

    The content of Employee Management System DFD level 1 must be in accord from the idea of context diagram. Then the context diagram will be broken down into its sub processes which 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 basis for the company admin to manage their Employees. These records are used in processes and were stored in the data store that you will see in the next level.

    With being knowledgeable about the DFD level 1 of the Employee Management System, you will know then its broaden context terms.

    In addition to that, this level shows how the inputs or data fed on the system were processed. Then you will be also informed about the outputs that the system gives.

    The processes shown in this DFD Level 1 were all based on the concept of the stated Employee management System Project.

  • Employee Management System Level 2

    After presenting the Employee Management System DFD levels 0 and 1, next in line is the level 2.

    Here’s what you need to consider in creating data flow diagram level 2 for Employee Management System.
    • DFD Level 2 should present the system basic component, database and flow of data between the processes in Employee Management.
    • Since the DFD level 2 is the highest abstraction level, Employee Management System processes must be detailed that is continuation of the DFD level 1.

    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 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 Management System DFD levels 0, 1 and 2.

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

What is Employee 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 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 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 the given requirements.

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