Integration Builder (IB) builds collaboration knowledge of cross-component Business Process Management (ccBPM).
Integration Repository (IR) holds Business Process Definitions and abstract interfaces.
Integration Directory (ID) holds Collaboration Profiles and Collaboration Agreements. The Process Editor stores Business Process Configuration and Routing Rules there.

The Runtime WorkBench monitors (performs "is-alive" checks) of components and enables customization of component runtime settings.
