Die Herausforderungen des Data Warehousing liegen langst jenseits von Grundkonzeption und Architektur, die weitestgehend gefestigt sind. Ein ganzheitliches proaktives Datenqualitatsmanagement und integriertes Metadatenmanagement sind fur ein effektives Data-Warehouse-System heute ebenso elementare Voraussetzung wie Datenschutz und Datensicherheit, die im Data-Warehouse-Umfeld neue Bedeutung erlangt haben. Zahlreiche Uberschneidungen und daher Synergiepotenziale bestehen mit Customer Relationship Management, Enterprise Application Integration und Knowledge Management.

Die Autoren zeigen zu diesem Zweck fundierte Konzepte und praktikable Losungen auf, die speziell im zweiten Teil anhand realer Umsetzungen mit bedeutenden europaischen Unternehmen (UBS, Credit Suisse, Swiss Re u. a.) verdeutlicht werden. "
