Online Banking System Activity Diagram | UML

Online Banking System Activity Diagram | UML

Online Banking System Activity Diagram – does a big part in the banking management system. This designed activity diagram shows the panel and reader on how would the banking system behave towards its users. It simplifies the development of Banking System with its corresponding UML Diagram that also assesses in explaining the activity.

It gives the overall overview of the processes and actions or activities that flow between the users and the system. You could also check from the activity diagram the correct processing of the banking system.

The UML activity diagram 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 user. 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 about it, let me tell you its purpose and role. The Online Banking System must have an activity diagram so that the programmers would have a basis on how should the software 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 a friendly and effective or easy-to-use software, then you must also complete the activity diagram.

Through the activity diagram, you’ll be able to illustrate the flow of activities and know what should be the interactions between the system and its users. Your readers and users will also be guided about how would they use the system by looking into its activity diagram. So its best for you to explain your thoughts ang correct flow of interactions on Banking System through activity diagram.

Activity Diagram Symbols:

Now before we create the Activity diagram of Banking System, you must know first the symbols used to make it. And here are the symbols used in Activity Diagram.

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

In addition to that, being familiar with these activity diagram symbols will help you show the detailed parts and interactions that should happen when you develop the System. Then this thought enables you to have right ideas on how you would develop the system that you want.

Additional Knowledge

The activity diagram works perfectly with the other UML Diagrams which were available also on our site. They are the Online Banking System Use Case Diagram, Data Flow Diagram, Entity Relationship Diagram and many more. These diagrams served as the blueprint designs to foresee the needed functions of a working Online Banking System.

Activity Diagram of Banking Reservation System

Now I present to you the designed activity diagram that the Banking System development must have. It contains the specific details of every activities or transaction done in during banking.

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

    Activity Diagram for Banking System
    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 programmer ideas and guides them on how would they 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 the hint on how should the banking system respond to their request or application.

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

    Activity Diagram of Banking System
    Now this activity diagram was designed for the Bank Member side of the system. It is essential for the system development to have separate activity diagram design but you could still combine all the design for the whole system. It was just separated here to give you more detailed type of discussion for every sides of the banking system.

    The designed banking system activity diagram for the member side was to emphasize the behavior of the system towards 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 towards 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 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.

You may also be specific with the activities that you want to see or be found on your desired system. But you can also merge them in one design. It is always up to you on what design you would like in creating your activity diagram for you Banking System.


It is essential for you to know the diagrams used to design and develop the Banking Reservation 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. But you can also specify them through merging the processes in one activity diagram design if you want, just make sure that they are clear and precise, and states the correct actions to emphasize the flow of the whole Banking System.


Now, what have you learned through our discussion? Have you determine the Diagrams that you must create? What project do you have in mind?

And if you have ideas or concerns with our discussion, do not hesitate to leave us your suggestions and questions. Those are highly appreciated. Thank you so much and have a good day!
