Administrators also need to log in, but inherit from ordinary users, don't you use the cable?
Qingrun 18:15:49
Yes, if you draw this inheritance relationship, then you don't have to draw a connection separately.

However, the problem on this picture is: You did not show the difference between regional administrators and system administrators.
Laugh 18:19:23
Yes it is

There is also a question is: whether the administrator has all the rights of users. Because many systems believe that administrators can do management, other operations such as browsing are just the right of users.
Smile 18:20:48
Does the administrator does not have common users commonly used?
Qingrun 18:19:16
This should be seen in the system, and different industry features are also related.
For example, in the business system, administrators is management system, managers, do not need him to buy things, shopping, or do other consumption and service, this time, it is necessary to consider the relationship between them.

Where is the text explains the permissions of each actor,
Qingrun 18:29:06
You can write in the note information of each Actor.
Qingrun 18:29:51
Alternatively, it is also possible to distinguish between use cases.
I am a personal opinion: there is too much inheritance in the system, it will be too rigid. Please consider carefully.
Smile 18:32:44
Oh
