UML A graphical notation Unified Modeling Language Unified the methods of its three principal designers: –Grady Booch –James Rumbaugh –Ivar Jacobson MADALINA CROITORU

UML A visual language for developing software systems Not a programming language The current standard is Two types of diagrams: –Structural modeling: static architecture –Behavioral modeling: interaction 13 (9) types of basic diagram types MADALINA CROITORU

Basic Terminology Model: abstraction of the underlying problem Domain: The actual world from which the problem comes Models: Objects that interact by sending each other Messages Objects have Attributes (things they know) and Behaviors/Operations (things they do) MADALINA CROITORU

Use Case Diagrams Describe what a system does from the standpoint of an external observer Is a summary of scenarios for a given task A scenario is an example of what happens when someone interacts with the system An actor: what / who initiated the event involved in the task MADALINA CROITORU

Sequence diagram Describes the dynamic interaction How operations are carried out: what messages are sent where and when Organized according to time MADALINA CROITORU

Statechart diagrams Objects have behaviors and states The state of an object depends on its current activity condition A statechart diagram shows the possible states of the object and the transactions that cause a change in state MADALINA CROITORU
