From the Back Cover
"The time has come for the consumers themselves to step forward and to specify a standard for meta data semantics and meta data exchange. This book is an important first step in that direction."
-W. H. Inmon, from the Foreword
The Common Warehouse Metamodel (CWM) is rapidly gaining momentum within the data warehousing and business analysis communities, and is being incorporated into the next generation of data warehousing products and tools. This new standard for meta data interchange, which was developed by the Object Management Group (OMG), provides for seamless integration of data warehouses-- a critical ingredient for sharing data within and across organizations.
This book provides a comprehensive and authoritative overview of CWM. The authors are among the key developers of the CWM standard, and they give you an intimate understanding of how to develop and implement CWM applications for data warehousing and business analysis. They also explain how CWM relates to both established and forthcoming standards for system integration and interoperability.
The book covers everything you'll need to know to begin planning your own CWM projects, including:
* An overview of the core metamodeling technologies that CWM employs, including Meta Object Facility (MOF), Unified Modeling Language (UML), XML Meta Data Interchange (XMI), and Interface Definition Language (IDL)
* How CWM extends the OMG Metamodeling Architecture into the data warehousing and business analysis domains
* Concrete examples of how CWM is used to model various real-world data warehousing applications
The Web site contains updates to the CWM technology, descriptions of tools, and links to vendors.
