Common Object Request Broker Architecture

(standard, programming)
(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.

Latest version: Corba 3.0.3 2004-03-12, as of 2007-09-04.

The CORBA architecture allows applications to make requests to objects in a transparent and independent of language, operating system, hardware, or consideration of location (MASTELARI, 2004).
Among the most notable, there are CORBA architecture used for optimal interaction between program components within network workstation backup, Volume Shadow Copy used for backing up open files, Rsync for optimizing the network traffic and backup time, and several others.
NetVoyant Enterprise Version 3 provides a scalable, distributable network performance management engine based on the CORBA architecture. Polling stations can be distributed across the enterprise, promoting better use of network bandwidth, as well as preventing polling bottlenecks.
At this meeting, the PTC initiated work on a standard that will integrate the new protocol SOAP with OMG's CORBA architecture. SOAP (Simple Object Access Protocol) transmits business data expressed in the eXtensible Markup Language (XML) over the widely-used web protocol HTTP.

Supplementing the UML, the MetaObject Facility (MOF) [4] provides a standard repository for metadata within the CORBA architecture. Defined in terms of a metamodel and set of IDL interfaces, the MOF supports component-based computing from modeling and design through implementation to run time.
Object Transaction Service (OTS) specification describes a service that supports flat and nested transactions in a distributed heterogeneous environment based on the OMG CORBA architecture. OTS defines interfaces that allow multiple distributed objects to cooperate to provide atomicity of transactions.
