The distributed object computing paradigm: concepts and applications

The computing world is shifting toward a new paradigm, the Distributed Obje ct Computing (DOC) paradigm. This paradigm exploits the benefits of object- oriented technology and uses the Internet and its communications infrastruc ture as a vehicle for the delivery of a wide range of sophisticated value-a dded distributed services. Applications of this paradigm are characterised as being open, client/server and multi-tiered applications using collaborat ing distributed objects. The integration of the Common Object Request Broke r Architecture (CORBA) and object-oriented programming languages such as Ja va will facilitate the introduction and deployment of such applications in a platform-independent distributed environment. In this paper, we introduce both CORBA and Java as tools to facilitate the development of DOG-based ap plications, and we present examples from two areas of applications, namely, telecom and electronic commerce (EC) applications.
