Common Warehouse Metamodel, An Introduction to the Standard for Data Warehouse Integration

Das Common-Warehouse-Metamodell (CWM) ist eine XML-basierte Technologie zum Datenaustausch aus Quellen jeder Art, unabhängig von der Plattform des Anbieters. Geschrieben von den Autoren der CWM-Spezifikation, bietet Ihnen dieses Buch eine gut verständliche Einführung in das Thema. Erklärt wird, wie Geschäftsbereiche mit Hilfe von CWM effizienter arbeiten können und mit welchen praktischen Schritten man CWM plant, implementiert und einführt. Sie erhalten einen Überblick über die Architektur von CWM und sehen, wie die einzelnen Komponenten in existierende Datenbanken und Data-Warehouse-Architekturen integriert werden können. Mit zugehöriger Website.
