Explain Object Flow in Activity Diagram

In the next video, you will learn about object flow.

In the previous video, you learnt about object flows, which help you see how objects are manipulated during the execution of an activity.

Video Transcript

Object flow in Activity diagram we can also represent how a particular object gets updated during an activity. For an example, in this particular case, let's take a case of supplier who raises his invoice and we have an invoice object right after raising the invoice. The invoice object could be in a state which is unpaid post that when an admin pays for that invoice, the object of state invoice could get updated to paid. This way we can represent an object getting updated during the flow of an activity.

Video Recap

• Object flow in an activity diagram can represent how a specific object is updated during an activity.

• An example of this is a supplier who raises an invoice, which creates an invoice object in an unpaid state.

• When an admin pays the invoice, the object state is updated to paid.

• This approach allows the representation of object updates during the flow of an activity.

In the next video, you will understand how to represent object flow in the activity diagram in draw.io.

In the previous video, you learnt how to draw object flow using draw.io.

Now you have learnt about object flow and their significance in the Activity Diagram. Object flow is used to represent how objects are manipulated during the execution of an activity.
