Use Case Diagram for the ATM System
Explore how to design a use case diagram for an ATM system by identifying main actors like cardholders and defining critical use cases such as inserting cards, verifying identity, and conducting transactions. Understand the relationships and workflow that ensure secure banking operations through the ATM.
We'll cover the following...
Let’s build the ATM system’s use case diagram and understand the relationship between its main actors and functions. First, we’ll define the different elements of our system, followed by the complete use case diagram.
System
