Select the role that you wish to add objects to. You may drag and drop objects from the Physical Schemata to the Objects section of the role editor. To assign privileges to a role select a role from the Roles section and then select an object in the Objects section. In the Privileges section check the rights you wish to assign to this role. For example, a web_user role might have only SELECT privileges and only for database objects exposed through a web interface. Creating roles can make the process of assigning rights to new users much easier.
