Represent a test condition to ensure that the control flow or object flow only goes down one pathīring back together different decision paths that were created using a decision-node. Represent an object that is connected to a set of Object Flows Stop all control flows and object flows in an activity (or action)

Portrays the beginning of a set of actions or activities Show the flow of an object from one activity (or action) to another activity (or action). Here is an example of a Swimlane activity diagram for modeling Staff Expenses Submission:

The registrar asks the student to pay for the initial tuition.Ī swimlane is a way to group activities performed by the same actor on an activity diagram or activity diagram or to group activities in a single thread.

The registrar helps the student to enroll in seminars.

The registrar informs student to attend in university overview presentation.

The registrar determines that the forms have been filled out properly.

The applicant hands a filled out copy of Enrollment Form.

An applicant wants to enroll in the university.

This UML activity diagram example describes a process for student enrollment in a university as follows: Activity Diagram Example - Student Enrollment The activity diagram example below visualize the flow in graphical form. Depending on the condition either the Overnight Delivery activity or the Regular Delivery activity is performed.įinally the parallel activities combine to close the order. On the Fill Order side, the method of delivery is decided conditionally. One side fills and sends the order while the other handles the billing.

Once the order is received, the activities split into two parallel sets of activities. Given the problem description related to the workflow for processing an order, let's model the description in visual representation using an activity diagram:

If a spreadsheet is necessary, open the spreadsheet package, create the spreadsheet, and paste the spreadsheet into the document.If graphics are necessary, open the graphics package, create the graphics, and paste the graphics into the document.Save the file under a unique name within its directory.The activity diagram example below describes the workflow for a word process to create a document through the following steps: Activity Diagram - Modeling a Word Processor
