Activity Diagram for Student Enrollment System

The UML activity diagram for student enrollment system is a diagram that presents the flow of system activities. It is one of the methods used to document the system behavior in terms of activities and development.

Additionally, the activity diagram uses symbols to define the overall workflow of the student enrollment system. It is composed of activities, decisions, and paths (flows).

What is a Student Enrollment System?

An online student enrollment system centralizes all the data in one place, making it simple to access and amend. Enrollment information is uploaded automatically to the database, so there is no need to type it in by hand.

The system is also meant to manage all of the actions involved in the student enrollment process. Its main goal is to help staff members sign up students and keep track of their information.

All in all, the system can manage registration, cash flow, student information, teacher reward, classroom resources, data searching, data analysis, and decision making. This can save the admin’s time and effort.

Define Student Enrollment System Activity Diagram

UML defines a student enrollment system activity diagram as a very effective behavior diagram. This diagram shows the flow of interaction between the system and clients. This is done by helping them visualize the system’s functionality in various degrees of detail.

The activity diagram in UML visually depicts a set of actions or control flows of a student enrollment system. It describes the processes in a use case diagram. Its’ illustration can also be sequential or concurrent.

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

Importance of UML Activity Diagram

The use of an activity diagram involves major activities that define the workflow of the project. These activities flow with user decisions that result in more effective interaction. It also visualizes a set of actions or control flows of a student enrollment system.

An activity diagram in UML represents the Student Enrollment System‘s major activities and constraints. Then these activities generate a flow that the project should include. Each activity was labeled properly to determine the system’s behavior.

The activity diagram is one of the Student Enrollment System UML diagrams. It also shows the system’s dynamic behavior. It shows the flow of messages from one activity to another.

Activity Diagram: Benefits

The Activity Diagram Benefits are as follows:

  • An Activity Diagram helps in understanding how an algorithm works.
  • It also describes 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.

Student Enrollment System Activity Diagram

The Student Enrollment System Activity Diagram example expounds on the system’s ideas. This activity diagram example using swimlanes is shown in the detailed illustration to enlighten the programmers.

It figures out the activities that happen when a user logs in to a system. This example illustration shows the activities and scenarios done in online booking. Thus, the actions and decisions included were all emphasized here.

As seen in the illustration, we used the swimlane with three partitions. The left portion shows the admin lane. It covers all the possible activities of an admin when using the system. Its container also symbolizes the scope of the admin’s control.

The right partition is used as the enrollee’s lane. This lane shows the enrollee’s actions and processes.

Now, the system’s scope and activities were placed in the middle. This is to show that the system acts as the middleman between the school personnel and the enrollees. Therefore, the system is designed to be accessible by the admin and the enrollees.

To access the system, the users must have their accounts logged into the software. The functions were then emphasized as the activities flow and the system and users communicate.

You can add more to this and it is up to you how will you create your activity diagram. But, make sure that you have precise information and include the important decisions (actions).

What are the Symbols used in Activity Diagram?

Activity Diagram Symbols – are used not just to draw an activity diagram, but also to emphasize the role of all that was included in the system’s process. Each of the symbols was used to present a certain part of the system.

Activity Diagram Symbols
Activity Diagram Symbols
  • Start – is the beginning of the action. It uses a filled circle symbol to show its function.
  • Action – is a stage of an activity in which users or software accomplish a certain task. Action is shown in Round-edged rectangles.
  • Decision – symbolizes a conditional branch in the flow. It has two or more outputs and a single input. A diamond symbol presents this notation.
  • Swim Lanes – are the lanes showing the actor’s boundaries. The activities drew in the same lane considered as the organization’s activities. Swim lanes must be in a logical arrangement.
  • Activity Flow – is another name for the connectors in the diagram that illustrate the flow between processes (activity).
  • End (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 also be much easier by using these Activity Diagram symbols.

How to Draw an Activity Diagram?

Time needed: 5 minutes.

Here are the steps in developing (designing) the activity diagram for student enrollment system.

  • Step 1: Familiarize Activity Diagram Symbols

    To draw an activity diagram, you need to familiarize yourself first with the symbols used. The symbols let you discuss the system’s flow of activities and interaction. Programmers can also quickly deliver the system’s concept to the users.

  • Step 2: Identify the flow of actions.

    After familiarizing the symbols used, you will need to identify the flow of actions. The flow of actions would be based on your use case diagram.

    Actions describe the sequence or series of activities when a user invokes the student enrollment. Moreover, the action represents a discrete unit of functionality in an activity diagram. It also describes the steps in a UML use case diagram.

    The incoming and outgoing activity edges of actions specify the control flow of data. Its actions begin when all of the input requirements are met.

  • Step 3: Add the Actors (users) involved.

    Actors carry out their actions on things, transforming them into other objects or changing their state. This actor is someone or something that interacts with the system from outside the system.

    We use “actors” as labels on the swimlanes to indicate that the action or step performed was from them or the system. This way will help readers and developers how will the system behave or interact with actors or vice versa.

  • Step 4: Trace the flow of activities.

    To trace the flow of activities, make sure that you know that flows can be sequential, branching, or run.

    Developers use action or control flows to know the transition from one state of activity to another. There might be several entering and outgoing action flows in this notation.

    Furthermore, control flow determines the activity’s flow, and the inbound arrow initiates a single activity step. Upon accomplishing this phase, the flow continues along the outgoing arrow. Object flow also describes the flow of objects (data) within activities.


In conclusion, we have discussed What is an Activity Diagram for Student Enrollment System and the steps on how to develop it. This activity diagram acts as one of the methodologies for creating a student enrollment system.

Additionally, an activity diagram stresses the system’s flow of activities and the interactions between the users and the system.

Therefore, using an activity diagram in UML will not only let you understand the project but also tell you the possibilities while designing it. This diagram works best with the other UML Diagrams which are provided in the Recommended Articles. See also other Activity Diagrams in the Related Articles below.
