RBAC (role-based access control, role-based access controls) is where users are associated with permissions through roles. Simply put, a user has several roles, and each role has several permissions. In this way, a "user-role-permission" authorization model is created. In this model, there are many-to-many relationship
Permission is the user's power to execute a function. In Oracle, permissions are divided into system permissions and entity permissions based on different system management methods. System permission refers to whether authorized users can connect to the database and perform system operations in the database. The entity permission refers to the user's
Role-Based Access Control (RBAC) is used to associate users with permissions through roles. Simply put, a user has several roles and each role has several permissions. In this way, the authorization model of "user-role-permission" is constructed. In this model, the relationship between users and roles and between roles
There are two different ways to add users: using the GRANT statement or directly operating the MySQL authorization table. The better way is to use the GRANT statement, because they are more concise and seem to have fewer errors. The following example shows how to use a mysql client to install a new user. These examples assume that permissions are installed by default according to the previous chapter. This

# Groupmod -G 102 group2
This command modifies the group ID number of group group2 to 102.Example 2:
# Groupmod –g 10000-n group3 group2
This command changes the identification number of the group group2 to 10000 and the group name to Group3.4. If a user belongs to more than one user group at the same time, the user can
