SMO Object Model
The SMO object model is made up of a hierarchy of objects. The Server object is the top level object and all instance class objects reside under the Server object.
The ManagedComputer class is a top level class with a separate object hierarchy. The ManagedComputer object represents Microsoft SQL Server services and network settings available through the WMI Provider.
The SMO object model is made up of several namespaces. For more information, see SMO Namespaces.
