Activity
UML specifies several types of behaviors:
•Activity
•State Machine
•Interaction
•Opaque Behavior, which has subtype FunctionBehavior
An Activity is a major task that must take place in order to fulfill an operation contract.
An activity can represent:
•An entire business process.
•A step in a business process.
•The invocation of an operation.
Activities can be decomposed into subactivities; the lowest-level Activity is considered a Task or Atomic Action.
Activities and flow of resources between Activities are modeled on Activity Diagrams.
