## Detailed Description

The IApplySchema interface defines the ApplySchema command, which creates or updates a feature schema within the DataStore. Input to the ApplySchema command is the feature schema instance to be created or updated. Optionally, a provider-specific IPhysicalSchemaMapping interface can be specified that can be used to control how the feature schema elements are mapped into physical storage.
