2 the operating system layer 6. a distributed system. and was a member of the architectural team that designed corba. a challenging error- handling case occurs when a client needs to know the outcome of a request in order to take the next step, after failure of a server. this can sometimes result in incorrect actions and results. tecture was developed in the early 1990s to counter this problem. the corba model provided a standard software platform on which distributed objects could communicate interact with each other seamlessly transparently. in this case an orb allows objects to publish their interfaces, it. this book breaks the mold. by taking the reader through the entire spectrum of the distributed object approach from requirements analysis through systems development with a thorough treatment of relevant standards. richard m soley technical director object management group. inside corba is a comprehensive authoritative guide to distributed object architecture software.
