Common Warehouse Metamodel 

The official guide to programming with the revolutionarydata-sharing technology

The Common Warehouse Metamodel (CWM) is the new OMG standard thatmakes the sharing of data seamless. The CWM standard developmentteam provides developers with a complete overview of what CWM isand how it works. After acquainting readers with the CWMarchitecture and how each CWM component fits into existing databaseand data warehouse architectures, the authors provide expertguidance on how to plan for, implement, and deploy CWMtechnologies.

Companion Web site features updates on CWM technologies, descriptions of tools, and links to vendor sites.
