Description

The official guide to programming with the revolutionary data-sharing technology
The Common Warehouse Metamodel (CWM) is the new OMG standard that makes the sharing of data seamless. The CWM standard development team provides developers with a complete overview of what CWM is and how it works. After acquainting readers with the CWM architecture and how each CWM component fits into existing database and data warehouse architectures, the authors provide expert guidance on how to plan for, implement, and deploy CWM technologies.
Companion Web site features updates on CWM technologies, descriptions of tools, and links to vendor sites.
