Question

Explain corba and its object model in distributed system

Answer 1

Answer:

CORBA is essentially a design specification for an Object Request Broker (ORB), where an ORB provides the mechanism required for distributed objects to communicate with one another, whether locally or on remote devices, written in different languages, or at different locations on a network.

Answer 2

Explanation:

The Common Object Request Broker Architecture (CORBA) is a standard developed by the Object Management Group (OMG) to provide interoperability among distributed objects. CORBA is the world's leading middleware solution enabling the exchange of information, independent of hardware platforms, programming languages, and operating systems.

Using CORBA, application components can communicate with one another no matter where they are located, or who has designed them. CORBA provides the location transparency to be able to execute these applications.

Using CORBA, application components can communicate with one another no matter where they are located, or who has designed them. CORBA provides the location transparency to be able to execute these applications.CORBA is often described as a "software bus" because it is a software-based communications interface through which objects are located and accessed. The illustration below identifies the primary components seen within a CORBA implementation.

Data communication from client to server is accomplished through a well-defined object-oriented interface. The Object Request Broker determines the location of the target object, sends a request to that object, and returns any response back to the caller. Through this object-oriented technology, developers can take advantage of features such as inheritance, encapsulation, polymorphism, and runtime dynamic binding. These features allow applications to be changed, modified and re-used with minimal changes to the parent interface.
