UML Activity Diagram

How To draw UML Activity Diagrams

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.

Symbols for create UML activity diagram

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.

UML Notation →

There are many ways to track the system in a critical situation. To model a system behavior, uml notation is widely used. Usually, an UML diagram consists of elements such as actor and a case. This diagram represents the structure of UML notations. Unified Modeling Language (UML) is used in software engineering to depict graphically the software modeling process. UM Language uses graphic notations for developing models of object-oriented systems. These notations displays requirements, sub-systems, logical and physical elements, etc. We created this diagram using ConceptDraw DIAGRAM reinforced with Rapid UML solution. It can be helpful for students on software engineering, when learning UML.UML Notation *

UML Tool & UML Diagram Examples →

You can use many tools to create a representation of a system behavior or a scheme of objects relationships. Some of them are quite abstract and useless, and some, like UML tools help clarifying both the structure and the behavior of a system. There are various types of uml diagrams and tons of examples explaining the difference between them. UML 2.2 specification has many kinds of diagrams. They are divided into two groups( structure and behavior diagrams). This class diagram shows the hierarchical structure of UML 2.2 specification. Class diagram - the most suitable tool for this task because it is designed to describe basic structure of a system. This diagram can be use as a visual aid for learning UML.UML Tool & UML Diagram Examples *

Activity Network (PERT) Chart →

Activity Network and Project Evaluation and Review Technique, or PERT, charts are a way of documenting and analyzing the tasks in a project. This diagram is constructed as part of the process in creating a schedule of corrective actions. The Activity Network Chart (PERT) shows the logical connections and consequence of tasks to be performed. It displays the time period for problem solving and the implementation of all activities through the critical path.Activity Network (PERT) Chart *
