Can ordinary administrators assign roles in the management system

Generally speaking, the roles used by CRM software can be flexibly assigned according to the needs and actual situation of the enterprise. The following are some common role types: Administrator: responsible for system configuration, data backup and permission management. Salesperson: responsible for handling sales opportunities, customer information, sales orders and other related business.

In the management system used by the enterprise, the user's operation permission is controlled by the role, and the role can be understood as a user group with certain operation authority.

In this model, there is generally a many-to-many relationship between users and roles, roles and permissions. As shown in the figure below: A background user role permission system can always be roughly divided into three modules: user management, role management and permission management.

However, by default, only the system administrator account can access these functions, and other user accounts need to manually assign administrator rights to use them. This article will introduce how to assign administrator rights to other accounts in the Windows system so that they can also enjoy the convenience of administrator accounts.

Ordinary users can't operate on any project in system management. You can add a role. The system administrator can set up an account, and then click the user in the permission to add.

Through the system outline design, what are the user roles in the system?

1. The user refers to the operator, and the role can be understood as a position. Roles can be given permissions. If the user has a role, he will automatically have all the permissions of the role. Therefore, the number of user roles is unlimited.

2. Roles are divided into internal system users and external system users. Internal: clerks and service personnel, technicians and professionals, supervisors, middle managers and senior managers. External system users: customers, suppliers, partners, employees.

The above section of 500) code also shows that this system analyst loves programming, which is an important feature that the engineering world is different from the college world.

What is role management in the system and what is its function

1. [Answer]: Roles are used to simplify the management of the complex task of assigning many permissions to many users. Roles allow users to accept the same database permissions in groups without assigning these permissions to each user separately.

2. Role can implement a unified management strategy for a group of people (all users under the role). Usually, efficient management is: first manage the role; then manage a special user in the role.
