Use Case Diagram for ATM Machine
The UML use case diagram is one of the methods used to show the processes involved in ATM machine. It depicts the system’s supposed structure and behavior.
Additionally, the diagram consists of processes (use cases) and users or “actors”. It uses defined symbols to describe the overall flow of the system.
Project Overview
| Name: | ATM Machine System Use Case Diagram in UML |
| System Users: | The expected users of the system are the bank admin, employee, and card holders. |
| Tools Used: | Any Diagram tools that provide use case diagram symbols. |
| Designer: | ITSourceCode.com |
What is a Use Case Diagram?
The UML use case shows the sample behavior of the software. It includes the project functions using use cases, actors, and their connections.
Moreover, the diagram assists you to define and organize project needs. This also provides a clear picture of the user and system relationships.
Importance of UML Use Case
Helping the developers and businesses with system management is one of the importance of the UML use case diagram for atm. It includes the procedures from the viewpoint of users.
Furthermore, the diagram serves as the system analysis to identify, clarify, and organize the project needs. This diagram works best with other UML Diagrams for ATM System. Other UML diagrams include activity, class, sequence, deployment, and component diagrams.
ATM Machine System Use Case Diagram
The use case has two main illustrations that describe the system’s general and specific processes using include and extend.
ATM System General Use Case Diagram
The general use case diagram for atm machine shows the main functions of the system. It is based on the transactions done during atm management.
The general use case is the most common application of a use case diagram. The use case diagrams depict the system’s main components as well as the flow of information between them.
Use Case Diagram for ATM System using Include and Extend
The use case diagram using include and extend is used to elaborate the proceeding diagrams.
The label include indicates that the sub-processes of the main processes must be included to complete the task, extend is otherwise.
Manage Customers’ Information and Status Use Case Diagram
This is the process where the admin (bank teller) monitors and manages atm card basic information.
Manage ATM Applicants’ Information Use Case Diagram
This process is where the user encodes and validates the cardholder applicants. The admin can also update the applicants’ financial transactions as soon as they passed the requirements.
Manage Withdrawing and Saving Transaction
This is the process where the bank/system admin processes their customer’s info to let them avail the bank and ATM services.
You can add more to this illustration and it is up to you how will you create your diagram. But make sure to have precise information and consider the included use cases.

How to draw a Use Case Diagram?
Time needed: 2 minutes.
Here’s the complete guide on how to draw a use case diagram for ATM system.
- Step 1: Familiarize Use Case Diagram Symbols
For beginners, you need to familiarize first with use case symbols to be used.
- Step 2: Determine the system processes
The next step is to determine the system’s processes. They will be the use cases of your project.
You may ask the users about the typical activities done in the ATM machine. - Step 3: Analyze the use cases included
The gathered information from the users needs to be evaluated to know the general use cases.
From the general use cases, you will see the sub-cases that are included. But, only include the useful processes related to the ATM system. - Step 4: Plot the Use Case Diagram
To plot the diagram you will need the users, use cases, container (scope), and their indicators (association). You will base the flow of use cases on the evaluated information from the users.
Your first move is to place the users involved.
Next, put the container in the plotted diagram to separate the objects (users and system) scope.
Then place the use cases of the ATM system.
Finally, you need to map out the association of the use cases to show the interactions between the user/s and the system.
Conclusion:
The UML use case diagram represents the methodology used in system development. It helps developers know the possible inputs that the project should process and perform.
Furthermore, the diagram is also applicable in modeling the software’s use cases (processes). It captures the system’s flow from one process to the next.
