Integration of Third-Party Applications and Web Clients by Means of an Enterprise Layer

Abstract

This case study presents an experience report on an enterprise modelling and application integration project for a young company, starting in the telecommunications business area. The company positions itself as a broadband application provider for the SME market. Whereas its original information infrastructure consisted of a number of stand-alone business and operational support system (BSS/OSS) applications, the project’s aim was to define and implement an enterprise layer, serving as an integration layer on top of which these existing BSS/OSSs would function independently and in parallel. This integration approach was to be non intrusive and was to use the business applications as-is. The scope of the case entails the conception of a unifying enterprise model and the formulation of an implementation architecture for the enterprise layer, based on the enterprise JavaBeans framework.
