Basic Behaviour Modelling
Chapter-5
,• A UML use case diagram is the primary form of system/software requirements for a new
program underdeveloped.
• Use cases specify the expected behavior (what), and not the exact method of making it ha
(how).
• It is an effective technique for communicating system behavior in the user's terms by spe
externally visible system behavior.
, Actor: It comes under the heading of use case diagrams. It is an object, such as a user, tha
interacts with the system.
Use Case: A set of operations carried out by a system to produce an observable output. In
model, it's used to structure behavior. It comes to pass as a result of collaboration.
