indication

An operation executed as a result of some action such as the creation, modification, or deletion of an object, access to an object, or modification or access to a property. Indications can also result from the passage of a specified period of time. An indication typically results in an event.

inheritance

A relationship between two classes in which all the members of the subclass are required to be members of the superclass. Any method or property supported by the superclass must also be supported by any member of the subclass. For example, Modem is a subclass of Logical Device.

instance

An object derived from a WBEM class that contains actual data. For example, in database terms, an instance is a row of data from a table.

instance provider

One of the roles of an object provider by which it retrieves, modifies, and enumerates the instances of system and/or provider-specific classes. Instance providers may also invoke methods. Also see class provider and property provider.

interface class

The class used to access a set of objects. The interface class can be an abstract class representing the scope of an enumeration.

ISA

An operator occurring within the WQL WHERE clause, asserting that an instance is a member of a particular class hierarchy.

Also see GROUP BY, HAVING COUNT, WITHIN, and the SELECT Statement ISA Operator.
