Notation ¡ Action state: represent the non-interruptible actions of objects ﺍﻓﺸﻴﻦ ﻻﻣﻌﻲ http: //ceit. aut. ac. ir/~lamei

Notation ¡ sub activity state: l ﺍﻓﺸﻴﻦ ﻻﻣﻌﻲ http: //ceit. aut. ac. ir/~lamei invokes an activity graph , to represent nested diagrams

Notation ¡ Arrows/Action Flow: relationships among action states. ﺍﻓﺸﻴﻦ ﻻﻣﻌﻲ http: //ceit. aut. ac. ir/~lamei

Notation ¡ Object Flow: refers to the creation and modification of objects by activities l l ﺍﻓﺸﻴﻦ ﻻﻣﻌﻲ http: //ceit. aut. ac. ir/~lamei from an action to an object: the action creates or influences the object from an object to an action: the action state uses the object

Notation ¡ Initial State l ﺍﻓﺸﻴﻦ ﻻﻣﻌﻲ http: //ceit. aut. ac. ir/~lamei represents the initial action state.

Notation ¡ Final State l ﺍﻓﺸﻴﻦ ﻻﻣﻌﻲ http: //ceit. aut. ac. ir/~lamei represents the final action state.

Notation ¡ Branching l l l ﺍﻓﺸﻴﻦ ﻻﻣﻌﻲ http: //ceit. aut. ac. ir/~lamei represents a decision with alternate paths. The outgoing should be labeled with a guard expression can also label one of the paths "else. "

Notation ﺍﻓﺸﻴﻦ ﻻﻣﻌﻲ http: //ceit. aut. ac. ir/~lamei

Notation ¡ Branch/Decision: can be used to merge decision branches back together (merge) ﺍﻓﺸﻴﻦ ﻻﻣﻌﻲ http: //ceit. aut. ac. ir/~lamei

Notation ¡ Splitting & Joining l ﺍﻓﺸﻴﻦ ﻻﻣﻌﻲ http: //ceit. aut. ac. ir/~lamei illustrate parallel transitions

Notation ¡ Swimlanes l ﺍﻓﺸﻴﻦ ﻻﻣﻌﻲ http: //ceit. aut. ac. ir/~lamei To group related activities into one column

Example ¡ Process Order l l l ﺍﻓﺸﻴﻦ ﻻﻣﻌﻲ http: //ceit. aut. ac. ir/~lamei order is accepted payment is accepted order is shipped
