Rapid UML solution extends ConceptDraw DIAGRAM software with templates, samples and libraries of vector stencils for quick drawing the UML diagrams using Rapid Draw technology.
"An activity in Unified Modeling Language (UML) is a major task that must take place in order to fulfill an operation contract. Activities can be represented in activity diagrams.
An activity can represent:
(1) The invocation of an operation.
(2) A step in a business process.
(3) An entire business process.
Activities can be decomposed into subactivities, until at the bottom we find atomic actions.
The underlying conception of an activity has changed between UML 1.5 and UML 2.0. In UML 2.0 an activity is no longer based on the state-chart rather it is based on a Petri net like coordination mechanism. There the activity represents user-defined behavior coordinating actions. Actions in turn are pre-defined (UML offers a series of actions for this)." [Activity (UML). Wikipedia]
The template "UML activity diagram" for the ConceptDraw PRO diagramming and vector drawing software is included in the Rapid UML solution from the Software Development area of ConceptDraw Solution Park.

"A sequence diagram is an interaction diagram that shows how processes operate with one another and in what order. It is a construct of a Message Sequence Chart. A sequence diagram shows object interactions arranged in time sequence. It depicts the objects and classes involved in the scenario and the sequence of messages exchanged between the objects needed to carry out the functionality of the scenario. Sequence diagrams are typically associated with use case realizations in the Logical View of the system under development. Sequence diagrams are sometimes called event diagrams, event scenarios." [Sequence diagram. Wikipedia]
This UML sequence diagram example was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Rapid UML solution from the Software Development area of ConceptDraw Solution Park.
