Activity Diagram for Online Banking System

The Activity Diagram for Online Banking System is an important part of the banking management system. This designed activity diagram shows the panel and reader how the banking system would behave towards its users. It simplifies the development of the banking system with its corresponding UML Activity Diagram that also assists in explaining the activity.

It gives an overall overview of the processes and actions or activities that flow between the users and the system. You could also use the activity diagram to make sure that the way the banking system works is right.

The essential actors or users of this banking system would be the customers or bank members, employees, and the bank admin. By determining the users of the system, it would be much easier for you to build the interactions and activities in the system.

Then you will be able to foresee the behavior of the system towards its users. So you should be aware that your system must be user-friendly and effective for its users.

What is an Online Banking System Activity Diagram?

To have a clear understanding of it, let me tell you its purpose and role. The Online Banking System must have an activity diagram so that the programmers have a basis on how the software should approach its users.

It is because the activity diagram guides the programmer in creating the software and its must-have behavior. So if you want friendly and effective or easy-to-use software, then you must also complete the activity diagram.

Activity Diagram Symbols:

Before we create the activity diagram of the banking system, you must first know the symbols used to make it. And here are the symbols used in the activity diagram.

You must be familiar with these symbols in order for you to distinguish what should go in the illustration to avoid misunderstandings. This is also to educate you about the activity diagram symbols so you and the users will understand the system’s behavior.

Now I present to you the designed activity diagram that the banking system must have. It contains the specific details of every activity or transaction carried out during banking.

  1. Designed Activity Diagram of Banking System for New Applicant and Employee

    This sample activity diagram shows the activities included for new applicant transactions. It illustrates the interaction of the system with the new applicant and the employee.

    Also, this gives the programmers ideas and guides them on how to design or develop the system interface for the new application for bank membership. 

    As you can see, the activity diagram designed for the applicant and employee side gives you an idea of how the banking system should respond to their request or application.

  2. Designed Activity Diagram of Banking System for Bank Members and Employee

    This activity diagram was designed for the bank member side of the system. It is essential for the system development to have a separate activity diagram design, but you could still combine all the designs for the whole system.

    It was just separated here to give you a more detailed type of discussion for every side of the banking system.
    The member side of the banking system activity diagram was made to show how the system works with the bank members. 

  3. Designed Activity Diagram of Banking System for Bank Admin

    And this activity diagram was designed for the admin side. This diagram shows and indicates that the system development includes security for the transactions made in the bank.

You should be informed that these diagrams can be modified to achieve your desired system behavior. You can also create your own unique system function to suit 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.

You may also be specific about the activities that you want to see or find on your desired system. But you can also merge them into one design. It is always up to you to decide what design you would like to use in creating your activity diagram for your banking system.


It is essential for you to know the diagrams used to design and develop the Banking Reservation System. This is due to the fact that without it, it is impossible to create a fully functional system.

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, but you will identify the processes that are required and connect them to the other UML Class Diagrams. For example, you can create your own UML case diagram for bank accounts.

By completing the Activity Diagrams per module or per process, you will easily achieve your desired system. But you can also specify them through merging the processes into one activity diagram design if you want.

Just make sure that they are clear and precise, and state the correct actions to emphasize the flow of the whole banking system.
