Object Request Broker (ORB)

The Object Request Broker (ORB) is middleware that uses the CORBA specification. The Object Request Broker or ORB takes care of all of the details involved in routing a request from client to object, and routing the response to its destination. The ORB is also the custodian of the Interface Repository (abbreviated variously IR or IFR), an OMG-standardized distributed database containing OMG IDL interface definitions. 

On the client side, then, the ORB provides interface definitions from the IFR, and constructs invocations for use with the Dynamic Invocation Interface (DII). It also converts Object References between session and stringified format, and (for CORBA 2.4 and later ORBs) converts URL-format corbaloc and corbaname object references to session references. 

On the server side, the ORB de-activates inactive objects, and re-activates them whenever a request comes in. CORBA supports a number of activation patterns, so that different object or component types can activate and de-activate in the way that uses resources best. 

Also see CORBA and OMG Interface Definition Language (IDL).

The CORBA Reference Guide: Understanding the Common Object Request Broker Architecture
by Alan Pope
Average Customer Review: 3.5 stars based on 3 reviews.
Customer Review: This is a good book for those who understand client/server or OO programming, but who haven't had exposure to CORBA. The book doesn't give enough depth to serve as a developer's reference guide. But, if you want a solid understanding of all aspects of CORBA without having to read through a 3-inch thick book, this is the book to pick.

by Ron Ben-Natan
Average Customer Review: 3 stars based on 2 reviews.
Customer Review: I found this book an excellent introduction to CORBA, and always recommend it to technical developers wanting to learn about CORBA. It doesn't compare CORBA to rival technologies nor talk about what CORBA will be able to do sometime in the future. Furthermore, it does not contain any cartoons of aliens - a great relief to many of us!
