 CORBA - a Whatis.com definition
Common Object Request Broker Architecture (CORBA) is an architecture and specification for creating, distributing, and managing distributed program objects in a network.
The essential concept in CORBA is the Object Request Broker (ORB).
ORB support in a network of clients and servers on different computers means that a client program (which may itself be an object) can request services from a server program or object without having to understand where the server is in a distributed network or what the interface to the server program looks like.

Our object model of the EMBL database is organised into five main packages, as shown in Figure 1, where each package holds a set of closely related classes with a common purpose.
CORBA object interfaces together with their operations and type of data are defined in IDL.
The basic model for managing live objects is to cache data instances read from the database, to register their primary key values, and to respond to queries based on the cached data.

CORBA uses an interface definition language to specify the interfaces that objects will present to the world.
CORBA then specifies a "mapping" from IDL (Interface Definition Language) to a specific implementation language like C++ or Java.

To this Thus, all CORBA objects are known only by their interface, also known as an Object Reference(Objref), and the implementation details are hidden.
Like CORBA objects, the ORB itself is specified using a set of interfaces, and with ORBs that follow the GIOP standard, they have the same interface.

 Software Magazine: Entering ORB-it - object request broker; Object Management Group's Common Object Request Broker ...
Today, many of these issues are addressed by the object request broker (ORB), a piece of middleware that tracks the access and use of objects in a distributed environment.
It allows objects to interact in a heterogeneous, distributed environment, independent of the platforms on which these objects reside and techniques used to implement them.
"This is why Corba 2.0 introduces the higher-level concept of a domain, which roughly denotes a set of objects that for some reason, be it implementational or administrative, are separated from some or all other objects," she says.

CORBA is the acronym for Common Object Request Broker Architecture, OMG's open, vendor-independent architecture and infrastructure that computer applications use to work together over networks.
CORBA applications are composed of objects, individual units of running software that combine functionality and data, and that frequently (but not always) represent something in the real world.
Clients access objects only through their advertised interface, invoking only those operations that that the object exposes through its IDL interface, with only those parameters (input and output) that are included in the invocation.

CORBA (Common Broker Request Architecture) is a special application of networks.
Common Object Request Broker Architecture, or CORBA, was designed to work with data, software etc (all "objects" in object oriented programming) of all sizes, shapes, colors and – not least in these days when it seems that the info tech development world consists of Microsoft at war with everybody else – brand names.
It’s not difficult for a software program to deal with objects on one computer or objects which can be found somewhere on the network to which the program is installed.

 CORBA (Common Object Request Broker Architecture) and the OMG (Object Management Group)
CORBA (Common Object Request Broker Architecture) is a standard for distributed objects being developed by the Object Management Group (OMG).
CORBA provides the mechanisms by which objects transparently make requests and receive responses, as defined by OMG's ORB.
The CORBA ORB is an application framework that provides interoperability between objects, built in (possibly) different languages, running on (possibly) different machines in heterogeneous distributed environments.

 Overview of CORBA
Object -- This is a CORBA programming entity that consists of an identity, an interface, and an implementation, which is known as a Servant.
CORBA IDL stubs and skeletons -- CORBA IDL stubs and skeletons serve as the ``glue'' between the client and server applications, respectively, and the ORB.
Object adapters can be specialized to provide support for certain object implementation styles (such as OODB object adapters for persistence and library object adapters for non-remote objects).

Competitors Distributed object computing extends an object-oriented programming system by allowing objects to be distributed across a heterogeneous network, so that each of these distributed object components interoperate as a unified whole.
These objects may be distributed on different computers throughout a network, living within their own address space outside of an application, and yet appear as though they were local to an application.
Java/RMI server objects are named using URLs and for a client to acquire a server object reference, it should specify the URL of the server object as you would with the URL to a HTML page.

Although vendors are lining up behind common object request broker architecture as a key tool for implementing Telecommunications Management Network strategies and providing interoperability between applications, carriers are still leery of the technology.
While this flexibility is attractive, CORBA's relative immaturity in the industry is not.
Telcos' previous attempts to use the technology have revealed "performance gaps that the carriers couldn't live with," said Cotrupe, although he said the continued evolution of CORBA systems bodes well for the future.

 Common Object Request Broker Architecture (CORBA) - Frontmatter
The Object Management Group has developed an architecture and specification for object technology use, management, interworking (the exchange of data between object models), and interoperability (the means of message exchange between object request brokers).
Products which are developed in compliance with this architecture and specification include an Object Request Broker (ORB) which enables objects to transparently make and receive requests and responses in a distributed environment.
These object services are a collection of services (interfaces and objects) that support basic functions for using and implementing objects, as well as common facilities.

CORBA automates many common network programming tasks such as object registration, location, and activation; request demultiplexing; framing and error-handling; parameter marshalling and demarshalling; and operation dispatching.
This makes client requests appear to be local procedure calls.
When a client invokes an operation, the ORB is responsible for finding the object implementation, transparently activating it if necessary, delivering the request to the object, and returning any response to the caller.
