What is ORB

Chapter 13
Handbook of Research on Social Dimensions of Semantic Technologies and Web Services
An object request broker (ORB) is a middleware technology that manages communication and data exchange between objects. 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 (Wade, 1994). The developers are only concerned with the object interface details. This form of information hiding enhances system maintainability since the object communication details are hidden from the developers and isolated in the ORB (Cobb, 1995).

Abstract
The potential growth of applications distributed over a network and the large number of users has created the need for an infrastructure which can support increasing interaction among such users and applications. In this environment a scalable solution is needed. This problem known as application integration is addressed in this chapter, and it is combined with Semantic Web technology. After introducing the different techniques to overcome the application integration challenge current trends in Semantic Web Services are discussed and the most recent R&D projects and a selection of available tools are presented. Also discussed is the use of ESB as a suitable mechanism to deploy Semantic Web Services.
