Rather, user interface integration, an approach in which integration takes place primarily in the mind of the user, can be a more favorable option. In this paper, CWT Connect, a travel management portal developed by Carlson Wagonlit Travel, is taken as a case of user interface integration. The paper starts with outlining frequent problems in integrating information systems and discusses how the portal metaphor is related to integration. The case of CWT Connect and its application at electrical engineering provider Cegelec is then depicted in detail.en-UKCase StudyInformatik330 - Wirtschaft005 - Computer Programmierung, Programme und Daten04B - Beitrag Konferenzschrift2594-2600
