UML Activity Diagram. Design Elements

UML Activity Diagram illustrate the business and operational step-by-step workflow of components in a system and shows the overall flow of control.
This vector stencils library contains 47 SysML activity diagram symbols.
Use it to design your SysML activity diagrams using ConceptDraw PRO diagramming and vector drawing software.
"Activity diagrams are constructed from a limited number of shapes, connected with arrows. The most important shape types:
- rounded rectangles represent actions;
- diamonds represent decisions;
- bars represent the start (split) or end (join) of concurrent activities;
- a black circle represents the start (initial state) of the workflow;
- an encircled black circle represents the end (final state).
Arrows run from the start towards the end and represent the order in which activities happen." [Activity diagram. Wikipedia]
The vector stencils library "Activity diagram" is included in the SysML solution from the Software Development area of ConceptDraw Solution Park.

This purchase order processing UML activity diagram was created on the base of activity diagram from the software architecture documentation wiki of the Software Engineering Institute (SEI) of Carnegie Mellon University (CMU).

"A purchase order (PO) is a commercial document and first official offer issued by a buyer to a seller, indicating types, quantities, and agreed prices for products or services. Acceptance of a purchase order by a seller forms a contract between the buyer and seller, so no contract exists until the purchase order is accepted. It is used to control the purchasing of products and services from external suppliers.
Creating a purchase order is typically the first step of the purchase to pay process in an ERP system." [Purchase order. Wikipedia]

"Alarm triggers.
The individual triggers for a car alarm vary widely, depending on the make and model of the vehicle, and the brand and model of the alarm itself (for aftermarket alarms). Since aftermarket alarms are designed to be universal (i.e., compatible with all 12 volt negative ground electrical systems as opposed to one carmaker's vehicles), these commonly have trigger inputs that the installer/ vehicle owner chooses not to connect, which additionally determines what will set the alarm off."

UML State Machine Diagram.Design Elements

UML state machine's goal is to overcome the main limitations of traditional finite-state machines while retaining their main benefits.
ConceptDraw has 393 vector stencils in the 13 libraries that helps you to start using software for designing your own UML Diagrams. You can use the appropriate stencils of UML notation from UML State Machine library.
The vector stencils library "UML activity diagrams" contains 37 symbols for the ConceptDraw PRO diagramming and vector drawing software.
"Activity diagrams are constructed from a limited number of shapes, connected with arrows. The most important shape types:
(1) rounded rectangles represent actions;
(2) diamonds represent decisions;
(3) bars represent the start (split) or end (join) of concurrent activities;
(4) a black circle represents the start (initial state) of the workflow;
(5) an encircled black circle represents the end (final state).
Arrows run from the start towards the end and represent the order in which activities happen.
Hence they can be regarded as a form of flowchart. Typical flowchart techniques lack constructs for expressing concurrency. However, the join and split symbols in activity diagrams only resolve this for simple cases; the meaning of the model is not clear when they are arbitrarily combined with decisions or loops."

While in UML 1.x, activity diagrams were a specialized form of state diagrams, in UML 2.x, the activity diagrams were reformalized to be based on Petri net-like semantics, increasing the scope of situations that can be modeled using activity diagrams. These changes cause many UML 1.x activity diagrams to be interpreted differently in UML 2.x." [Activity diagram. Wikipedia]

UML Notation

Unified Modeling Language (UML) is a language of graphic description for object modeling in the field of software engineering. UML was created for definition, visualization, designing of software systems. UML is an open standard that uses graphic notations for creating visual models of object-oriented software systems.
Two types of diagrams are used in UML: Structure Diagrams and Behavior Diagrams. Behavior Diagrams represent the processes proceeding in a modeled environment. Structure Diagrams represent the elements that compose the system.
