'''Activity chart''' is a graphical „diagram that shows activities and actions to describe workflows" (Glossary of Key Terms). Workflow is a [[work]] sequence [[process]]. This is a specific position of a state diagram in which mostly or all of the elements have an activity effect (or subactivity) and in which mostly or all of the proceedings are caused by ended of the activities or subactivities. The main function is to concentrate on flows pushed by interior processing (UML Revision Task Force s. 299). Using activity chart, without knowing the domestic informations ( they are demanded by collaboration diagram), is really useful to understand the first-class execution [[attitude]] of structure (Booch G. i in. 1999, s. 31). We can use activity diagrams when all or most of events end internally ("that is, procedural flow of control"). Normal diagrams ( state diagrams)  are used for asynchronous operations (UML Revision Task Force s. 299).
== Constructions ==
Activity chart consists of a certain number of window form, that are connected together by arrows.  Below are the most commonly used and most important window shapes (OMG Unified Modeling Language Superstructure Specification, s. 414-415) :
* ''Initial state'' - a black dot, used as starting point 
* ''[[Action]]'' - ellipse/rectangle with rounded corners, it concerns the performance of an action
* ''Arrows'' - indicate the order of performing the action
* ''ControlFlow'' - two ellipses conected by arrow
* ''Decision'' - rhombus or diamond, gives you the opportunity to choose
* ''Start ''or ''Ened Synchronal Activities''''' - '''black bars, show the activities carried out at the same time'''
* ''FlowFinal'' - a circle with an "x" in the middle
* ''Fork'' - resembles a fork made of arrows, holds up synchronous activities
* ''The End'' - a black circle surrounded by a second circle
