Task3: CORBA

CORBA

CORBA is Common Object Request Broker Architecture. It is standard distributed object architecture developed by the object Management Group (OMG).

CORBA object differ from typical programming language objects in these ways:

• CORBA objects can be located anywhere on a network.
• CORBA objects can interoperate with objects on other platforms.
• CORBA objects can be written in any programming language for which there is a mapping from OMG IDL to that language.

CORBA object Interface

All CORBA objects support an IDL interface. It defines as object type. An interface can inherit from one or more interface. It is very similar to Java and C++.

An IDL interface declares a set of client accessible operations, exceptions, and typed attributes (values). Each operation has a signature that defines its name, parameters, result, and exceptions. A simple IDL interface that describes the classic "Hello World" program, follows.

module HelloApp

{

  interface Hello

  {

    string sayHello();

    };

};
