Rdb. It is a database originally developed by the late, great Digital
Equipment Corporation for its VMS operating system. Digital sold Rdb to
Oracle. Digital was bought by Compaq and Compaq by HP. Both VMS and
Rdb are still growing strong. (Rdb does run on some operating systems
other than VMS, but by far most installations of it are on VMS.)

The scope of a group defines two characteristics:
It determines the level of security applying to a group.

It determines which users can be added to a group.
Windows Server 2003 supports the following scopes:

Domain Local: Domain local groups are used to assign permissions to local
resources such as files and printers. Members can come from any domain.

Global: Members of this group can access resources in any domain. Members
can only come from the local domain.

Universal: Members can be added from any domain in the forest. Members can
access resources from any domain. Universal groups are used for managing
the security across domains. Universal groups can also contain global
groups. Universal groups are only available in the domains having
functional level Windows 2000 native or Windows Server 2003.
