Linking Classes Together

WMI providers are usually designed to provide information about a specific managed object on a single computer. If there is a common property that can serve as a key to uniquely identify all the different source instances, then use the View Provider to combine properties from different classes, namespaces, or computers into a single class.

You must first register the View Provider. After registration, you can create the following types of view classes:

• Join view

  Instances of different classes connected by a common property value.

• Association view

  Views of existing association classes across the namespace boundary.

• Union view

  Union of one or more instances.
