Use Case Diagram - Use Case Notation
This section describes the Use Case Notation used in a UML Use Case Diagram. A Use Case Notation presents a set of activities performed by actors on an object. When it is completed, a use case will yield a result that can be observed.
A Use Case Notation is the primary graphical notation used in a UML Use Case Diagram to represent a set of activities performed by actors on an object. When it is completed, a use case will yield a result that can be observed.
A Use Case Notation is drawn as an ellipse with the use case name placed inside. For example, "Order Food" is a set of activities on a restaurant object involving several actors like client, waiter, chef, etc. This set of activities can be drawn as a Use Case in a UML use case diagram as shown below:
