What are Activity Diagrams? Check out the following implementation examples

An activity diagram or activity diagram is a type of diagram in the UML that is used to describe the dynamic aspects of a system. Activity diagrams are basically flowcharts to represent the flow from one activity to another. Activities can be described as the operation of the system.

To better understand what an activity diagram is and how it’s used, see the full explanation in this article!


Activity diagram is basically a design flow of activity or work flow that is used on a running system. It is also used to group or define the display flow of the system. Inside there are components with a certain shape that are connected via arrows. The arrow then points to the order in which the activities are performed from start to finish.

Model Elements in Activity Diagrams

There are several elements of the model as follows.

Activities (activity). An activity is a container element that describes the highest level of behavior in an activity diagram . An activity contains activity nodes and activity edges that represent the sequence of tasks in the workflow that generate the behavior.
Actions (action). In UML, an action represents Chief and VP of Training Email Lists a separate unit of function within an activity.
Control nodes (control nodes). A control node is an abstract activity node that coordinates the flow of control within an activity.
Object nodes (object nodes). S node objects are abstract activities that help define the flow of objects within an activity. The object node indicates that an instance of the classifier may be available at a certain point in the activity.
Activity edges (activity edges). Activity edges are directional connections between two activity nodes. When a certain action in an activity is completed, the edge of the activity continues the flow to the next action in the sequence.

When are Activity Diagrams Used

In UML, activity diagrams provide a view of the behavior of a system by describing the sequence of actions in a process. It is similar to a flowchart in that it shows the flow between actions in an activity. However, these diagrams can also show parallel or concurrent flows and alternative flows.

In an activity diagram , you use activity nodes and activity edges to model the flow of control and data between actions. This is especially helpful in the following project phases.

Before starting a project, you can make it CRYP Email List possible to model the most important workflows.
During the requirements phase, you can create this diagram to illustrate the flow of events described by the use case.
During the analysis and design phases, you can use them to help determine the behavior of operations.
Activity diagrams can also be used for various needs as follows.

Model workflows using activities.
Modeling business needs.
High-level understanding of system functionality.
Investigate business requirements at a later stage.

Implementation Example
To better understand how to make activity diagrams , consider the following examples!

Document Creation in Word Processing Applications ( Word Processor )
The following example of an activity diagram describes the workflow of a word processor for creating documents. The steps are as follows.
