Hello:

In the petstore architecture, I have a question regarding Figure 18 User Creation Object Interaction Diagram.
There is no Actor in this sequence diagram. Why is it so? Can anyone please explain

Hi Subu,

I think that the intention of this diagram is show the interation between the architeture's components. Because of it, it wasn't need show the actor.
But for more information you can visit the AgileModelling web site.
