UML Activity Diagram. Design Elements
UML Activity Diagram is a type of Behavior Diagrams that graphically describes decomposition of the some activity on the components.
Activity Diagrams are used in modeling of business processes, technological processes, sequential and parallel computations.
UML Activity Diagram allows to show the sequence, branching and synchronization of processes.
To design UML Activity Diagrams use the following shape types:
- rounded rectangles to describe the actions;
- diamonds to describe decisions;
- bars to represent the start or end of the activities that occur at the same time;
- black circle to indicate the start of the workflow;
- encircled black circle to indicate the end of the workflow;
- arrows to represent the order in which activities happen.
Activity Diagrams were a specialized form of the State Diagrams in UML 1.x. In UML 2.x, the Activity Diagrams were reformed and now are based on Petri net-like semantics that allows to model a lot more situations.
The 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 an Activity Diagram use the UML Activity Diagram library.
UML Activity Diagram library contains 37 shapes:
- Object
- Data store
- Central buffer
- Expansion region
- Control flow (direct)
- Control flow (smart)
- Object flow (direct)
- Object flow (smart)
- Divider
- Decision/Merge
- Time event action
- Send signal node
- Receive signal node
- Expansion node
- Pin

ConceptDraw Rapid UML solution provides UML Activity Diagram library of vector stencils for activity diagram design elements like rounded rectangles of activities, diamonds of decisions, bars of the start (split) or end (join) of concurrent activities, black circle of the start (initial state) of the workflow, encircled black circle of the end (final state), etc.
Use UML Activity Diagram library to draw your own activity diagrams that show the business and operational stepwise workflows of components in your system.
All libraries for creating UML diagrams are available inside the ConceptDraw DIAGRAM Templates and samples are located in the Rapid UML section of ConceptDraw STORE.

A model of a system is defined as a set of hierarchical diagrams representing the asynchronous process of data transformation from the moment it is input to the system to the moment it is output to the user. To demonstrate how a process transforms the initial data, you should design a data flow diagram using a DFD Library included in ConceptDraw DIAGRAM Solution Park. Start your diagramming experience now!
You can use this library of symbols related to data flow diagrams (DFD) to design data-oriented or process-oriented models along with data process diagrams. This vector objects library It is a part of ConceptDraw solution designed for data flow diagramming, along with corresponding samples and templates. A data flow diagram is a 2D flowchart that depicts the sequence of particular activities and operations operations and activities which is accompanied by the dynamic flow of some data.

Starting producing workflow diagram from template you save time and avoid the blank page syndrome. At first, the workflow template is set of rules for a workflow. The workflow symbols used in the specific case are part of workflow template. This is the subset of large standard collections of workflow symbols. The first part of workflow template is identification of symbols allowed in use in your specific case. The best way would be to collect them in your customized drawing collection of workflow symbols which used in your specific cases of workflow diagrams. Another way to create business process documents is using business process flow diagram which have similar purposes and have different visual notation.
ConceptDraw DIAGRAM is professional workflow diagram software with the rich extentions from ConceptDraw Solution Park. The basic solution for workflow diagramming is Workflow Diagrams Solution. It delivers a rich set of workflow diagram templates and samples help you draw diagrams e

In software engineering, it is important to understand how the system would cooperate with external sources, like data sources. To give this information a visual representation, data flow diagrams (DFD) were used for years. The entire system is usually divided into smaller ones, and all of them process data flows in appropriate ways.
The visualizing business processes which engages the data transfer, is commonly preformed using DFDs (data flow diagrams). DFD is used to show the data flow processing and transformation. This DFD represents the electronic system of a customer purchase. It was created using Gane/Sarson notation. Data flow diagrams helps you to sort through and clarify transferring process making it available for analysis, and representation. ConceptDraw DFD solution introduces the vector library, containing the full set of icons from DFD notations.
