I guess that's in the eye of the beholder. That FAQ, for example,
starts from basics AFAICS.

RedGrittyBrick has linked up to what looks like decent introductory
work.

Are there any CORBA articles at IBM Developerworks?

CORBA, or Common Object Request Broker Architecture, is a standard
architecture for distributed object systems.

I want to know example of such "distributed object systems". This i=

s

what I don't understand. What kind of system are those ?


An object, in Java terms, is an instance of a class. A distributed
object system is one that instantiates objects on different hosts,
possibly even in different languages.

A purely Java CORBA system would host just Java objects on potentially
separate hosts, allowing clients to use those objects without having
to be in the same JVM.

For your convenience , here is what my line of thinking says..

Can I say mainframe application is a "distributed object systems" ?
[ I guess not]


No. It's strictly about "objects" in the sense of object-oriented
programming - a software concept.

Can I say application developed in Lotus notes is a "distributed
object systems" ? [ I guess not]


Why do you think it might be? Why do you think it might not be?

I am not clear with what is "distributed object systems" . Here is
the problem.


"distributed" - hosted on multiple hosts
"object" - instance of a class
"system" - coherent set of interacting agents and processes

I also did a Google search for this alsohttp://www.google.co.in/search?hl=

=en&q=distributed+object+systems&aq=...

But the results are not upto the mark and satisfactory. if you really


Picky, aren't we?

have a nice link which explain this stuff in particular are welcome.


I doubt I could find a link that would meet your standards.
