Student Management System DFD (Data Flow Diagram)

Student Management System DFD (Data Flow Diagram)

The Student Management System Data Flow Diagram (DFD) makes it easier to present the overall flow of data and their transformations. These transformations occurs as data enters and exits the system. The inputs, processes, and outputs are used to describe and define the whole Student Management System DFD.

To elaborate the Student Management System DFD, data flow diagram make use of DFD levels. This DFD Levels elaborates the flow of data inside the Student Management System from general concept up to specific description.

Student Management System DFD – Project Name and Details

What is a Student Management System Project?

Student Management System Project is proposed and developed to improve the productivity of schools that will use it. This project will help the users in student management, processing enrollments and providing a quality service not only to the students but also to the parents. It would be much easier for the School administrators and staffs to handle task by using Student management System Project.

The Student Management System Data Flow Diagram is one of the blueprint used for system’ development. It represents the system’s major processes and alternatives that generate the flow of data within. The data included in the Data Flow Diagram was labeled properly to guide the developers on the graphical representation of the Student Management System. 

Importance of DFD for Student Management System

The importance of DFD for Student Management System is that it improves audience’s understanding about what will happen in the student management. This is done by helping them visualizing the system’s data management at various levels of elaboration.

The data flow diagram helps in describing the flow of data in Student Management System. It denotes the steps involved in transferring data from the input to file storage and report output as its results.

The student management system data flow diagram involves major levels to elaborate the flow of data within the project. These levels has their part in expounding the details of the system’s data flow structure. This structure will be the guide of the developers in designing the system’s data handling.

DFD Diagram of Student Management System

The DFD Diagram of Student Management System consist of three main Level. Each DFD Level elaborates the data that flows within the system. These diagrams clarifies the description of data management in the project.

Student Management System DFD Level 0

The Student Management System DFD Level 0 also known as context diagram shows the main concept in a single process. It consist of the projects entities (users) and the general process and data flow. This context is explaining how the project work in just one look. The users feeds data into the system and then receives the output from it.

In this data flow diagram you will see the general process done in student management. This will also serve as a guide as you go through the deeper processes of the student management system data flow diagram. Its concept will be widened and specified in the next levels.

Student Management System DFD Level 1

The Student Management System DFD Level 1 is the wider view of the context diagram. Its’ role is to clarify the idea presented in DFD level 0. This level widens the single process by discovering its included processes and plotting the data that’ll pass through them.

This diagram reveals to you the initial transformation of data from being an input into an output. It also informs you that the included external entities has their contribution and request to the system in doing its task. There are entities that only fed data into the project, some are only waiting for outputs but others are doing both.

The DFD diagram Level 1 could either be the highest abstraction or not. It depends on the project analyst if they need to expound their project content until they reached the desired project function.

Student Management System DFD Level 2

The Student Management System DFD Level 2 is defined as the project’s highest abstraction. This is because it completes all the details needed to fulfill the overall function of the project. It’s the highest form of blueprint used ,to design the project’s core function.

Software Engineers used DFD Level 2 to complete the information and instruction in designing a well-functional system. Its because, the Level 2 has all the components needed in completing the project. It has the entities, processes and databases which will generate a path that leads the flow of data that enters and exits the System.

How to build Data Flow Diagram for Student Management System

Time needed: 5 minutes.

Steps in building a Data Flow Diagram for Student Management System.

  • Step 1: Familiarize Data Flow Diagram (DFD) Symbols

    Data Flow Diagram – describes the movement of data through a system or process. It contains data inputs and outputs, as well as data repositories and users. Their symbols and applications must be familiarized before you build the Data Flow Diagram.

    External Entity : is an external system (users) that provides or receives information and communicates with the system. They are the origins and destinations of data entering and exiting the system. They could be a third-party company or individual, a computer system, or a business system. Terminators, sources, sinks, and actors are all terms used to describe them.
    Process : is any procedure that transforms data and generates an output. It might execute calculations, sort data according to logic, or direct data flow according to business standards.
    Data Store : are database tables serves as examples of files or repositories that store information for later use. Each data storage is given a basic label, such as “Items” or “Location”.
    Data Flow : is the path taken by data between external entities, processes, and data repositories. It depicts the interface between the other components. It’s represented by arrows and labeled with a data name.

    Each of these data flow diagram symbols shows the overall data handling. Emphasizing the System’s structure would be much easier by using these Data Flow Diagram symbols.

  • Step 2: Determine the targeted users

    After the symbol familiarization, you’ll need to determine your targeted users. Your targeted users will be the ones to use your project.

    Your project is Student Management System then your users would be the School admin, students and School Staff. You may ask the users of the common activities that they do when doing task in student. These information will help you in proceeding with the next step.

  • Step 3: Analyze the processes and data included

    Analyzation is very important in creating data flow diagram. It will help you understand the work of the diagram and avoid the unwanted errors.

    The gathered information from the users are very useful in creating the diagram. You will evaluate the data and pick the general processes.

    From the general processes, you will see the possible data that will enter and exit the system. But only include the useful data and processes related to Student management. Then you’re ready for the next step.

  • Step 4: Plot the Data Flow Diagram

    To plot the data flow diagram you will need the users, processes, databases, and data flows. You will base the flow of data from the evaluated information to have the exact Data Flow Diagram.

    To do this, you’ll need to place first the users involved, main process and the data flow they will perform. This will first generate the DFD Level 0 or the context Diagram.

    Then you will deepen the idea in DFD Level 0. To perform this, you will figure the sub-processes that completes the main process. You will also add the data store that will serve as storage of the processed data. After that, you will trace the flow or path of data to know the transformations of data inputs into outputs. This will create the DFD Level 1.

    The highest abstraction of data flow diagram is the DFD Level 2. It will only be performed when DFD level 1 needs to be elaborated. This is done by adding the supporting processes in DFD Level 1. You will connect them to the existing level to give more elaboration to the Data Flow Diagram.


It is essential for you to know the diagrams used to design and develop the Student Management System. That is to help you create a fully-functional system with use of DFD. Creating DFD will help you perceive included inputs and outputs that the system should process and transform. Not only that, you will be able to connect its diagram to other Diagrams.
