Relationships

a box drawn around the use cases to denote the edge or boundary of the system being modeled
use case

things that the actors can do with the system
actors

roles played by people or things that use the system
include
- <<include>>
- a behaviour that is incorporated into the use case.
- not optional behaviour
- generalization
- only use to simplify the model
contraints - preconditions

specifies what must be true before the use case can start
contraints - postconditions

specifies what will be true after the use case has execuded
Flow of events - start
- when an actor does something to trigger the use case
- <actor><function>

<number> The <something><some action>
workflow - if statement
- <number> If <boolean expression>.
- <number>.<number> The <something><someaction>
workflow - for / while
- <number>. For <iteration expression>
- <number>.<number> The <something><someaction>
- <number>.<number + 1> The <something><some action> <number + 1>
