What is the Difference Between Activity Diagram and Flowchart

The main difference between activity diagram and flowchart is that activity diagram is a UML behavior diagram that represents the workflow of stepwise activities of the system while flowchart is a graphical diagram that represents the sequence of steps to solve a problem.

What is the difference between activity diagram and state chart diagram?

Both activity and state chart diagrams model the dynamic behavior of the system. Activity diagram is essentially a flowchart showing flow of control from activity to activity. A state chart diagram shows a state machine emphasizing the flow of control from state to state.

What is Activity diagram?

An activity diagram visually presents a series of actions or flow of control in a system similar to a flowchart or a data flow diagram. Activity diagrams are often used in business process modeling. They can also describe the steps in a use case diagram. Activities modeled can be sequential and concurrent.

What is the difference between activity and action in activity diagram?

Actions. Action is a named element which represents a single atomic step within activity, i.e. that is not further decomposed within the activity. Activity represents a behavior that is composed of individual elements that are actions. Note, that call behavior action may reference (call) activity.

What is activity diagram example?

Activity diagram is another important diagram in UML to describe the dynamic aspects of the system. Activity diagram is basically a flowchart to represent the flow from one activity to another activity. The activity can be described as an operation of the system.

Is related with state diagram?

Related Articles. A state diagram is used to represent the condition of the system or part of the system at finite instances of time. It's a behavioral diagram and it represents the behavior using finite state transitions. State diagrams are also referred to as State machines and State-chart Diagrams.

How do you do an activity diagram?

How to Draw an Activity Diagram

1. Step 1: Figure out the action steps from the use case. Here you need to identify the various activities and actions your business process or system is made up of.
2. Step 2: Identify the actors who are involved. ...
3. Step 3: Find a flow among the activities. ...
4. Step 4: Add swimlanes.

What are the elements of activity diagram?

Basic components of an activity diagram

• Action: A step in the activity wherein the users or software perform a given task. ...
• Decision node: A conditional branch in the flow that is represented by a diamond. ...
• Control flows: Another name for the connectors that show the flow between steps in the diagram.

What is a diagram example?

In science the term is used in both ways. For example, Anderson (1997) stated more generally: "diagrams are pictorial, yet abstract, representations of information, and maps, line graphs, bar charts, engineering blueprints, and architects' sketches are all examples of diagrams, whereas photographs and video are not".

What are Swimlanes in activity diagram?

A swimlane diagram is a type of flowchart that delineates who does what in a process. Using the metaphor of lanes in a pool, a swimlane diagram provides clarity and accountability by placing process steps within the horizontal or vertical “swimlanes” of a particular employee, work group or department.

What is merge in activity diagram?

Merge node is a control node that brings together multiple incoming alternate flows to accept single outgoing flow. There is no joining of tokens. Merge should not be used to synchronize concurrent flows.

How loop is represented in activity diagram?

There are 3 different notations that you can use.

1. As your loop is based on some elements (folders, documents) the most convenient way is to use Expansion Region (of iterative type).
2. Second option, that is a preferred choice when you have some guard based loop is a Loop Node.
