It doesn’t matter how the system is actually implemented, as long as it looks like this to the user.' The lines between the actors and the use cases represent the interactions.

The ellipses represent the use cases, which are descriptions of valuable work that can be performed with the system. (These can even be other computer systems, as is the case with “ATM.”) The box represents the boundary of your system. Use case diagrams are intentionally simple to prevent you from getting bogged down in system implementation details prematurely.Įach stick person represents an “actor,” which is typically a human or some other kind of free agent. You can think of a scenario as a question that starts with: “What does the system do if.?” For example, “What does the auto-teller do if a customer has just deposited a check within the last 24 hours, and there’s not enough in the account without the check having cleared to provide a desired withdrawal?” Each of these “situations” is referred to as a scenario, and a use case can be considered a collection of scenarios.

'If you are designing an auto-teller, for example, the use case for a particular aspect of the functionality of the system is able to describe what the auto-teller does in every possible situation. This example of bank ATM UML activity diagram was created on the base of UML use case diagram of automated teller machine from the course 'Thinking in Java, 2nd edition, Revision 9' by Bruce Eckel published on the website of the Computer Science and Electrical Engineering Department of the University of Maryland, Baltimore (UMBC). More experienced users will appreciate a full range of vector stencil libraries and ConceptDraw DIAGRAM's powerful software, that allows you to create your ATM UML diagram in a matter of moments. The ATM UML Diagrams solution is useful for beginner and advanced users alike. UML works as a general-purpose modeling language for software engineers or system analysts, offering a number of different diagram styles with which to visually depict all aspects of a software system.ĬonceptDraw DIAGRAM diagramming software, enhanced and expanded with the ATM UML Diagrams solution, offers the full range of icons, templates and design elements needed to faithfully represent ATM and banking information system architecture using UML standards. This is done most effectively by creating a Unified Modeling Language (UML) diagram, using object-oriented modeling.

Before the software code for an ATM, or any other system design, is written, it is necessary to create a visual representation of any object-oriented processes. In particular, the interaction of bank customers with an automated teller machine (ATM) can be represented in a Use Case diagram. UML diagrams are often used in banking management for documenting a banking system.
