CORBA

November 1991, Object Management Group (OMG) which is the organization responsible for standardizing promoting third estate Object Request Broker Architecture (CORBA) to answer to the engage for interoperability among the rapidly proliferating number of hardware and software products available today. In this essay, we will briefly illustrate CORBAs features and its architecture. After that, readers will win more familiar with CORBA and understanding the CORBA architecture. 1. Distributed Systems Before we discuss CORBA, 1 grievous concept we must know about it which is distributed systems. Actu blow ensembley, Distributed systems have been around, in wiz form or another, for some(a) time, although they havent always been called that and they certainly havent always had the flexibility that they do now. To spot where CORBA fits in, lets briefly fetch the history of distributed systems. Before distributed systems appeared, there were trio different system models. At beg inning, Monolithic Systems and Mainframes are on with come hierarchical database systems and dull terminals also known as green screens. Because of it, Software systems written for mainframes were often monolithic. That is the substance maltreater interface, business logic, and data access functionality was all contained in ace large application. By reason of this, one more fictile model came into being which Client/ horde Architecture is. With the advent of the PC made possible a dramatic double shift from the monolithic architecture of mainframe-based applications, some(prenominal) applications simply did not guide the massive power of mainframes. So client/server applications typically distributed the components of the application so that the database would absorb on the server (whether a UNIX box or mainframe), the user interface would lie on the client, and the business logic would reside in either, or both, components. However, one problem appeared is client/server was not without faults of its own, because d! atabase access functionality (such as embedded...
