A central concept in the Integration Framework  architecture is the adapter-based access to the service implementation. This creates an abstraction layer for the services.

The Abstraction Layer is comprised of a set of programmatic components and interfaces that the framework interfaces leverage for accessing the physical services.  The Abstraction Layer manages access to the physical services to provide a general and consistent way for accessing services from the framework interfaces.  The adapters’ role is to allow new services to be easily added or existing services modified.
