Re: (ROSE) Actors and Roles

[Derek Etherton]

Hi, Actors do tend to represent specific "roles" rather than actual individuals, i.e. in real life a person may have several differing roles or responsibilities, for example a programmer, may also be a team leader, a system administrator, and a user. These would typically be separate actors since they show particular "roles" that person adopts within their job/interaction with the "system".   Different roles/actors will typically require different uses from the system, and will therefore be individual actors interacting with different use cases.   You've also got the option of using inheritance with actors which allows for conditions where several actors share a common role when interacting with particular use cases.   Hope this helps,   regards,   Derek   ----- Original Message ----- From: pooya zahadat To: [EMAIL PROTECTED] Sent: Monday, August 27, 2001 6:32 PM Subject: (ROSE) Actors and Roles Hi Is it true : one actor can play different roles? can one role be share between two actors that play some other roles or actors must be different in all roles?  thanks
