A role is a collection of privileges that you assign to a user or group. Each user within an organization has a specific role, whether the user is a developer, administrator, basic user, or advanced user.
For example, the PowerCenter Developer role includes all the PowerCenter Repository Service privileges or actions that a developer performs.
You assign a role to users and groups for the domain and for application services in the domain.
If you organize users into groups and then assign roles and permissions to the groups, you can simplify user administration tasks. For example, if a user changes positions within the organization, move the user to another group. If a new user joins the organization, add the user to a group. The users inherit the roles and permissions assigned to the group. You do not need to reassign privileges, roles, and permissions.
