In addition to locating objects over a network, CORBA enforces fundamental object-oriented design: low-level details are encapsulated (hidden) from the client.

Clients access objects only through their advertised interface, invoking only those operations that the object exposes through its IDL interface, with only those parameters (input and output) that are included in the invocation.РІР‚Сњ In contrast, the implementation of an object-its running code, and its data-is hidden from the rest of the system (i.e., encapsulated) behind a boundary that the client may not cross. The essence of CORBA, beyond being a networked object broker, is the separation of the interface (syntax for communicating with an object) from the instance (the specific object): РІР‚СљThe interface to each object is defined very strictly. CORBA objects communicate via a message interface, described by the Interface Definition Language (IDL). CORBA competes with MicrosoftРІР‚в„ўs proprietary DCOM. Joshua Feldman, in CISSP Study Guide (Third Edition), 2016 CORBAР”В¬ommon Object Request Broker Architecture (CORBA) is an open vendor-neutral networked object broker framework by the Object Management Group (OMG). For example, while CORBA is implemented as a client/server communication model, a layer (called an event service) has been added that emulates the publish/subscribe behavior.Р”В®ric Conrad. Services are continually being added to the ORB structure that extend the capabilities of CORBA.

Components can also be integrated that are not object-oriented (such as legacy code) by wrapping the code in a layer that provides an object-oriented interface.

Its main benefits are that it has a well-accepted standard for the interface, it allows for interoperability of software components written in different languages (including Java and C++) and/or running on different platforms, it handles all network communication protocols, and it provides for run-time reconfiguration of software components. Some high-level features of CORBA, however, make it very attractive for future control engineering products used to integrate systems. (2000) for details on the development of a product that is based on a CORBA substrate. The use of CORBA in control engineering is rather new see Wills et al. The middleware itself is available in different languages that all abide by the CORBA standard for example, the Java 2 Platform Standard Edition, v1.3, includes a CORBA ORB. In this manner, the calling object does not need to know the location of the remote object. When an object calls a method of another object distributed elsewhere on the network, the ORB intercepts the call and directs it. A basic feature of CORBA is the Object Request Broker (ORB) that handles remote procedure calls. OMG has approximately 800 member companies who develop and adopt products that abide by the standards set forth by OMG.
