Activity Diagram for Student Management System

Student Management System Activity Diagram is one of the UML models used to describe the system’s activities. It shows the system’s behavior by presenting the flow of activities from one to another. The possible flow of activities can be in order, split, or continuous.

Activity Diagram for Student Management System uses symbols to define the overall workflow of activity diagram. It is build up of activities, decisions, and paths (flows).

Importance of Student Management System Activity Diagram

The importance of Student Management System Activity Diagram is that it enables interaction between developers and clients. This is done by helping them visualize the system’s functionality in various degrees of detail.

The activity diagram involves major activities to define the workflow of the project. These activities comes with user decisions that results to more effective interaction. Being a programmer, these are the important roles that the Student Management System should have.

UML Activity Diagram Student Management System

The UML Activity Diagram for Student Management System is one of the methods used for project development. It represents the system’s major activities and constraints that leads to paths that the project includes.

They were labelled properly to guide programmers and users about the behavior of Student Management System.

Additionally, activity diagram depicts software operations as a series of actions. These diagrams are used to document and define the system processes and use cases.

It can clarify difficult use cases to simplify and improve any process. An activity diagram also models the system’s actions, functions, and processes.

Activity diagrams provide the same basic goals as the other UML diagrams. It illustrates the system’s dynamic behavior. The flow of messages from one object to another is shown in other UML diagrams.

The activity diagram on the other hand, shows the flow of messages from one activity to another.

Student Management System Activity Diagram: Benefits

The Activity Diagram Benefits are as follows:

  • An Activity Diagram helps in understanding how an algorithm works.
  • It describe the steps that a UML use case takes.
  • Shows how users and the system interact in a process or workflow.
  • Clarify difficult use cases to simplify and improve any process.

Activity Diagram of Student Management System

The Activity Diagram Student Management System is given to expound its ideas. This Activity Diagram using swimlanes are shown in different scenarios and is based on its users.

Student Management System Activity Diagram (Student Side) – This illustration shows the activities and scenarios done when the Student access the system. The actions and decisions included were all emphasized here.

Activity Diagram for Student Management System (Student Side)

This designed activity diagram shows the flow of activities and interactions between the system and the student. It is made to show you the ideal activities that happens in the student management system.

This provides initial ideas to help you set all the needed activities in the system and design them to your activity diagram for student.

Student Management System Activity Diagram (School Administrator side) – This diagram now shows the series of scenarios while using the student management system.

It illustrate the activities or events done when the system is in use. The system design is able to show you the functions for the school admin side.

Student Management System Activity Diagram (School Administrator Side)

This diagram shows the interaction between the School Admin and the system in terms of managing students’ information.

The interaction shows various activities such as adding student information, updating the existing data and validating their information.

This designed activity diagram for the school management system illustrates the behavior of the system towards the school administrators.

You have to declare in the activity diagram about what will you develop in the system for the admin side. This is to provide security to the system.

You should be informed that these diagrams can be modified to achieve your desired system behavior. You can also create your unique system function to justify all of your clients needs.

And if you want, you can copy all the ideas presented here so you won’t need to create a new one.

Steps in creating an Activity Diagram for Student Management System.

  • Step 1: Familiarize Activity Diagram Symbols

    Activity Diagram Symbols – are used to create an Activity Diagram which were presented here. Their symbols and applications must be familiarized before you build the Activity Diagram.
    Activity Diagram Symbols
    • Start – is the beginning of the action is symbolized by a filled circle. A dark circle represents the initial node.
    • Action – is a stage of an activity in which users or software accomplish a certain task. Actions are represented by round-edged rectangles.
    • Decision – represent by a diamond and is used to symbolize a conditional branch in the flow. It has two or more outputs and a single input.
    • Swim Lanes – are the lanes drawn as boundaries, and the activities drawn in the same lane as the organization’s activities. Swim lanes must be arranged in a logical order.
    • Activity Flow – is another name for the connectors in the diagram that illustrate the flow between processes (activity).
    • End or Terminator – is the last phase of the activity. An indicated black circle represents the final node.

    Each of these activity diagram symbols shows the overall System behavior. Emphasizing the System’s behavior would be much easier by using these Activity 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 for school, then your users would be the Staff, Admin and the students. You may ask them of the common activities that they do when doing task in recognizing faces. These information will help you in proceeding with the next step.

  • Step 3: Analyze the activities included

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

    The gathered information from the targeted users are very useful in creating an activity diagram. You just need to evaluate these data and pick the general activities.

    From the general activities, you will see the specific activity that are included in it. But only include the useful activities and decisions (circumstances) related to student management. Then you’re ready for the next step.

  • Step 4: Plot the Activity Diagram

    To plot the activity diagram you will need the users, activities, decisions, and their flows (paths). You will base the flow of activities from the evaluated information to have the exact Activity Diagram.

    To plot your Activity diagram, you need to place first the users involved and the process they will perform.

    Then place the figured activities or steps included in doing the process.

    After that, you will trace the flow or path of activities to know the series of interaction between the user/s and the system.

    Finally, you put the swim lanes or the partition in the plotted diagram to separate the objects’ (users and system) activity. This is to identify what are the activities or decisions that are under them or should be performed.


It is essential for you to know the diagrams used to design and develop the Student Management System. That is because you cannot perfectly create a fully-functional system without it.

But if you create this activity diagram, you will know the possible inputs and scenarios that the system should process and perform. Not only that, you will find out the needed processes and connect them to the other UML Diagrams.

By completing the Activity Diagrams per module or per processes, you will easily achieve your desired system.
