Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In distributed computing, an object request broker (ORB) is a piece of middleware software that allows programmers to make program calls from one computer to another via a network. ORBs promote interoperability of distributed object systems because they enable users to build systems by piecing together objects- from different vendors- that communicate with each other via the ORB. ORBs handle the transformation of in-process data structures to and from the byte sequence, which is transmitted over the network. This is called marshalling or serialization. Some ORBs, such as CORBA-compliant systems, use an Interface Description Language (IDL) to describe the data which is to be transmitted on remote calls.
