UML Activity Diagram illustrates the business and operational step-by-step workflows of components in a system and shows the overall flow of control.
Activity diagrams are constructed from a limited number of shapes, connected with arrows. The most important shape types:
rounded rectangles - represent activities;
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.
ConceptDraw has 393 vector stencils in the 13 libraries that will help you to start using software for designing your own UML Diagrams.
You can use the appropriate stencils of UML notation from UML Activity library with 37 objects.
The example "Design elements - UML activity diagrams" is included in the Rapid UML solution from the Software Development area of ConceptDraw Solution Park.
Example 1. Symbols for create UML activity diagram
Quick and easy designing the UML Activity diagrams of any complexity. Simply drag the needed objects to the document and arrange them to make a desired activity diagram.
In the case of using the offered template or sample, you need to choose the most suitable for you from the set and change it according to your needs to accomplish UML diagram.
Sample 2. Create UML activity diagram
ConceptDraw Rapid UML solution from the Software Development Area provides UML Activity Diagram samples, templates and library of vector stencils.
Use ConceptDraw DIAGRAM diagramming and vector drawing software enhanced with Rapid UML solution from ConceptDraw Solution Park to create your own UML activity diagrams that show the business and operational workflows of components and overall flow of control in your systems.

If you ever tried programming, you could face a lot of problems as a beginner. To help yourself, create a flowchart to follow an algorithm logic. Flowchart represents a program as a sequence of steps depicted in special symbols for each type of action.
This image of the interactive diagram made in ConceptDraw DIAGRAM applying the Live Objects technology. The diagram shows the effect of Selection Sort algorithm. The left part of the chart is the input area. The diagram in the central part of the drawing is a flow chart showing of the selection sort algorithm. The flowchart includes basic flowchart symbols, that represent various stages of algorithm. The flowchart symbols are connected with arrows ended lines, that depict the direction of the process flow. On the right side — the result is displayed.
The AWS Architecture Diagrams solution includes icons, sample and templates for several Amazon Web Services products and resources, to be used when creating architecture diagrams. The icons are designed to be simple so that you can easily incorporate them in your diagrams and put them in your whitepapers, presentations, datasheets, posters or any technical material you like.

Functional modeling allows to make complex business processes simple. One of the basic methods is IDEF0 and one of the most effective also. To create a business model, use flowchart symbols.
The IDEF0 library, supplied with ConceptDraw IDEF0 Diagrams solution contains 18 IDEF0 basic notation symbols. All symbols are the vector graphic images what means, that one can customize their size preserving the stable quality. Another library of IDEF0 symbols can be find out in the the Business Process Diagrams solution, included to the Business Processes section of ConceptDraw Solution Park. These libraries composed from just vector objects and are totally compatible. You can apply the IDEF0 symbols from both libraries at your flowcharts, if needed.
This sample is a UML Class Diagram that shows the banking system. The classes represented as boxes with attributes and are connected with dependency and synchronous message associations. The associations are indicated with the multiplicity 1..*. This sample can be used by the banks, by financial enterprises.
UML Component Diagram illustrates show components are wired together to larger components and software systems that shows the structure of arbitrarily complex systems.
Rapid UML Solution for ConceptDraw DIAGRAM contains 13 vector stencils libraries with 393 interactive shapes that you can use to design your UML diagrams.
To design a Component Diagram use the UML Component Diagram library.
UML Component Diagram library contains 36 shapes
