[Full modeling] relationship between roles and packages in the use case diagram

(15:11:18) Snow-hunting

Hi, could you give me a question? Do you have time?

(15:05:12) qingrun

Please.

(15:14:06) Snow-hunting

In Rose, there are various relationships between the role and the package. What is the relationship between the role operation package?

(15:08:10) qingrun

This parameter is not required. In general, it is the use, so you do not need to mark it. Unless this actor is an external system.

(15:16:03) Snow-hunting

I mean, what connection is used, which one can be used for solid-line and dotted-line arrows?

(15:09:38) qingrun

Oh. The solid arrow is enough.

(15:16:36) Snow-hunting

Oh

(15:10:35) qingrun

Generally, solid arrows are used.

(15:17:48) Snow-hunting

Oh, use the solid-line arrow to remind you that it must be a use case or class.

(15:11:11) qingrun

Oh. No, right? Let me see.

(15:18:05) Snow-hunting

The dotted arrow is not prompted.

(15:11:40) qingrun

Are you connected to a package? Not a use case.

(15:18:39) Snow-hunting

Yes, it's a package.

(15:12:18) qingrun

Clearly stated. Haha. Use the dotted arrow.

(15:19:13) Snow-hunting

Why?

(15:12:51) qingrun

Because it does not represent a direct connection relationship. It indicates the relationship between the actor and the use cases in the package.

(15:19:51) Snow-hunting

Oh

(15:20:02) Snow-hunting

Thank you.

(15:14:15) qingrun

I did not see any information in this regard. However, I use this method to represent it.

The key to the Language lies in the use of unity, rather than the deliberate demand for completeness. Haha

(15:21:48) Snow-hunting

Yes. Can I draw three roles into one package?

(15:15:20) qingrun

Yes.

(15:22:18) Snow-hunting

Oh
