Q) A person A sits in front of his computer and tries to buy a book from Amazon.com. My question is this: will A be the only actor in this case?

Hi Amr, Actor would not be "A" but the "Person" who would represent all the actors like "A".Remember, actors are not individual human beings, but they are "roles" which people play. Hope this helps, Sandeep SCJP2, OCSD(Oracle JDeveloper), OCED(Oracle Internet Platform)

Amr: That depends on number of factors, particularly the perspective you take and systems boundaries that you agree upon. For the scenario you have presented ... it seems to me that everything else (amazon.com) is the system. Only actor is a Person. As Desai has mentioned A is of Class Person so it could be more appropriate to call your actor a Person rather then A. Regards.
