Objectives At the completion of this subject students should have an in-depth understanding of distributed object programming concepts and techniques and the software engineering principles and architectures used for developing these systems; master the issues involved in distributed programming and development of multi-language distributed object environments; identify how distributed object programming techniques impact on program design, performance, fault tolerance and maintenance of these systems; and appreciate the current nature of distributed object systems, identify future industry trends and gain experience in the use of the object services provided by the object request broker.
Synopsis This subject investigates the use of techniques in distributed object software development and how they are used to implement networked applications. Topics covered include multi-language interoperability through the use of IDL, object migration and duplication, synchronous and asynchronous method invocation, types of distributed software architectures, persistence and exception handling across program boundaries. Throughout comparisons of differing distributed object programming techniques will be made to highlight the advantages and disadvantages of different distributed object systems. Example implementations may include OMG's Common Object Request Broker Architecture (CORBA), IBM's Distributed System Object Model (DSOM), Sunsoft's Distributed Object Environment (DOE), Microsoft's Common Object Model (COM) and Object Linking and Embedding (OLE).
