CORBA Core, Services & Facilities
The strength of CORBA stems from a solid core, augmented by a broad family of standardized interfaces, developed over the last 7 years by OMG
The core layer is given by the ORB model and the associated support to enable remote object invocation
On top of the ORB layer, CORBA offers the Common Object Services (COS) layer
On top of the COS layer, CORBA offers Common (Horizontal) and Vertical Market Facilities
The whole collection is functionally equivalent to an object-oriented distributed operating system
