The service is the first of the two security services, Group and User. The Group service represents the group account that has access permissions to a secured database and it has a Name property to identify it.

The second interface is the The word 'Supplier' in the interface name identifies the group object as a container for users. The container returned here is a collection of all users that belong to this group.
