CORBA for Not Yet Techies 2"Computer Careers: High Tech Jobs To Make the Internet Your Own Personal Network"by Richard Stooker, President Info Ring Press and author of Secrets of Changing to a Computer Career |

Version 1.1 of CORBA was introduced in 1991 and defined the Interface Definition Language (IDL) and the Application Programming Interfaces (API). Version 2.0 of CORBA was adopted in December of 1994 specifies how it can interoperate with ORBs from different vendors. The (ORB) establishes the client-server relationships between objects. It's an intrinsic part of CORBA. The ORB is a "gofer." If you the user tell it to go for coffee, it doesn’t come back until it’s got a cup of hot java for you. And you don’t care whether it got it from the cafeteria downstairs or a restaurant on the other wide. On the Internet, there’s little difference. And, given its object programming orientation, it is likely that the coffee is delivered to you via the programming language Java. CORBA is language-neutral – designed to support all languages for anyone with a computer jobCORBA is also considered "object neutral." Which means that even though it uses and is designed to take advantage of object oriented programming, it can also work with data and programs that are not object oriented. To make this clearer, there is a CORBA "success story" posted on OMG’s web siteCNN has a subsidiary named CNN Interactive. They are 150 people responsible for all non-broadcast dissemination of news for CNN. This apparently means they put together special reports and, probably background information and historical footage when necessary. They also use these resources to provide content to over 150 co-branded websites and to over 65,000 users in other news organizations. Apparently they have a good part of the market for stock footage for news reports and special reports made by anybody. They are based in Atlanta, GA, but they have computers located not only in their headquarters, but throughout North America, Europe and other locations throughout the world. These computers also use many different systems. Their content comes in to CNN in a variety of formats such as text, video and audio as well as other electronic formats. It must be stored and made accessible to CNN's internal users and external buyers of information. (I worked for a newspaper years ago, so I know that newspapers used to keep a "morgue file" of clippings on public figures. This was how reporters used to research people. Obviously these morgue files are now kept on computer and are more than simply old clippings.) The sheer quantity of information and its variety of formats, and the variety of hardware and software being used by all the various clients who needed access to the information posed a huge challenge. CNN Interactive wanted to be able to make the data accessible to all their different computers, to all the ones used by their reporters who needed background for news stories, and for all their customers. They decided to use it and, according to OMG, are very happy with it. CORBA - Page 3 |
