A domain is a virtual node in the Management Console tree that you use to group other nodes. The Management Console contains a default root domain. You can use domains to create a visual representation of the structure of the databases within an organization.
You can create an unlimited number of domains in the Management Console tree. A domain can contain other domains, databases, and server child nodes. You can set user permissions on domain nodes.
You can add, edit, cut, copy, paste, and remove a domain. You cannot remove the root domain. Drag a domain up or down in the Management Console tree to change the position of the domain within the tree.
