UML Activity Diagram

UML Activity Diagram is a type of UML diagrams, which illustrates the business and operational step-by-step workflows of components within a system and shows the overall flow of control. UML Activity Diagram is constructed from a limited number of shapes, connected each other with arrows. The most important shape types are rounded rectangles, diamonds, bars, black circle, encircled black circle. The arrows represent the order in which activities happen and run from the start towards the end. ConceptDraw DIAGRAM software enhanced with Rapid UML solution is ideal for software designers and software developers who need to draw the UML Activity Diagrams and other types of UML diagrams. It is convenient to use the appropriate stencils of UML notation from the UML Activity library included to the Rapid UML solution of ConceptDraw Solution Park and containing a lot of specific vector UML objects. Use them to design your own UML Activity Diagrams, make them colorful and attractive with style tools of ConceptDraw DIAGRAM software.

Flowchart design
A flowchart is a type of diagram which represents an algorithm, process or workflow, displays the steps as boxes of various kinds and depicts their order by connecting them with arrows. Any business graphic document will be more colorful and understandable if will use professional-looking and visual diagrams and flowcharts. Flowchart design gives versatile presenting and explaining of the process. ConceptDraw DIAGRAM flowchart software enhanced with Flowcharts solution helps effectively make Flowchart Design. Use of predesigned flowchart symbols and bright color palette offers a fresh view and favorably distinguishes the flowcharts designed in ConceptDraw DIAGRAM from the black and white flowcharts on a paper. Preferably to use no more than three or four colors and apply identical for the same shape types. The best flowchart design can be achieved by starting with Flowchart template, or any of suitable ready examples or samples offered in ConceptDraw STORE, open one of them and enter the proper text into each Flowchart shape. Each symbol of the flowchart has a definition that can't be changed. This means that all flowcharts shapes can be grouped in according to their meaning. Users with ConceptDraw DIAGRAM flowchart software can style groups of symbols with close definitions by color sets chosen from complementary palette. Almost all workflows can be depicted as a flowchart. Colored diagrams are more light for perception of the certain information, this is part of flowchart design. Bright colors need to be used in the key points of Decision symbols, to focus attention on their importance for whole process flow.

Diagramming Software for Design UML Activity Diagrams

Activity diagram describes the business and operational step-by-step workflows of components in a system. An activity diagram shows the overall flow of control.
The vector stencils library "Bank UML activity diagram" contains 32 shapes of UML activity diagram.
Use it for object-oriented modeling of your bank information system.
"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 diagrams may 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 an open standard, the language of graphic description used for modeling objects in a field of software development and software engineering. It was created for definition, specification, visualization, designing and documenting software systems, as a unification of three object-oriented technologies Booch, OMT and OOSE, and uses the defined graphic notation for creating the visual models of object-oriented software systems. Description of UML consists of two parts, interactive and supplementing each other: UML semantics, which represents a certain metamodel, defines the abstract syntax and semantics of terms of object modeling with UML, and UML notation that is a graphic notation for visual representation of UML semantics. The powerful tools of the Rapid UML solution included to ConceptDraw Solution Park make the ConceptDraw DIAGRAM diagramming and vector drawing software the best for easy applying the UML notation when creating the visual models of object-oriented software systems and designing different kinds of UML diagrams.
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."
