Can I extend actor in use case? for example I have "normal user" , "student user" and "teacher user"... every use case the "normal user" uses it ,by default the "student user" and "teacher user" use it too.. so can I extend "normal user" for "student user" and "teacher user" ? is that popular ? Thanks a lot :)
推荐答案
是的,例如,您可能有数据库管理员和Active Directory管理员。
Yes, for example, you may have a Database Administrator and an Active Directory administrator.
您可以将新模型的基本需求系统管理员排除在外,以简化模型。
You can factor out the common needs to a new base actor "System Administrator" for a simplified model.
您可以像其他任何角色一样表示角色概括,用实线画一条实线,该箭头从专用角色指向基础角色。
You can represent the actor generalisation like any other, draw a solid line with a closed arrow pointing from the specialised actor to the base actor.
