3 3 Diagrams A diagram is a view into a model Presented from the aspect of a particular stakeholder Provides a partial representation of the system Is semantically consistent with other views In the UML, there are nine standard diagrams Static views: use case, class, object, component, deployment Dynamic views: sequence, collaboration, statechart, activity
Sequence number
8 8 Collaboration Diagram “who sends to whom” Captures dynamic behavior (message- oriented) – not “when”
9 9 Collaboration Diagram Captures dynamic behavior (message- oriented) Purpose Model flow of control Illustrate coordination of object structure and control
Example: Change Flight Itinerary ( Use case description )
Sequence diagram for making a hotel reservation
Collaboration diagram for making a hotel reservation
UML Statechart Diagram Automata:
action
Statechart Example: Login part of an online banking system. Logging in consists of entering a valid social security number and personal id number, then submitting the information for validation.
UML Activity Diagram
Example: Activity Diagram – work flow, operation Captures dynamic behavior (activity-oriented) Building a house activity Syntax not defined in UML Semantics: Evaluate expression Send a method Create or destroy an object Synchronization bars Change of state or attribute Parallel activities
Example Activity: “Withdraw money from an ATM.”
