(foldoc) | Common Object Request Broker Architecture
CORBA
(CORBA) An Object Management Group
specification which provides a standard messaging interface
between distributed objects.
The original CORBA specification (1.1) has been revised
through version 2 (CORBA 2) with the latest specification
being version 3 (CORBA 3). In its most basic form CORBA
consists of the Interface Definition Language (IDL) and the
Dynamic Invocation Interface (DII).
The IDL definition is complied into a Stub (client) and
Skeleton (server) component that communicate through an
Object Request Broker (ORB). When an ORB determines that a
request is to a remote object, it may execute the request by
communicating with the remote ORB.
The Corba IDL can be mapped to a number of languages including
C, C++, Java, COBOL, Smalltalk, Ada, Lisp,
Python, and IDLscript. CORBA ORBs are widely available
for a number of platforms. The OMG standard for inter-ORB
communication is IIOP, this ensures that all CORBA 2
compliant ORBS are able to interoperate.
