An ideal model of data interchange based on a real mode

Abstract

There are industrial sectors that have been working with traditional EDI systems during the last decades. One of these is car manufacturing. The traditional EDI legacy systems mainly link hub companies and first tier suppliers. During the last years new technologies and techniques have been developed that introduce vital changes in B2B: the Internet, the web and XML Legacy systems mean costly investments and still work satisfactorily; but 42H has to include all the supply chain companies, and all production sectors. This document tries to introduce an ideal model that, taking into account legacy systems, shows the way towards a full integration for enterprises o f all sizes and kind o f activity. This model is a projection o f a real model already developed and working: ComprasAuto, developed by the Centre for Innovation and Services of Galicia (Spain) as an order from CEAGA, a cluster of first and second tier Galician companies in the supply chain of Citroen production plant in Vigo (Galicia).
