Mastering Data Warehouse Design: Relational and Dimensional Techniques ReviewI've been to seminars by Inmon, Kimball and Imhoff, as well as read many of their books. Kimball on the one hand, is generally clear and concise on the subject and obviously understands not only DW design and implementation concepts, but how they relate to various businesses and how the business really uses the data. He's also a fairly humble man in person.
Both Inmon and Imhoff on the other hand are rather self-aggrandizing (Inmon once waltzed into one of his keynote speeches dressed like a boxer to the theme from Rocky!), and both Inmon and Imhoff seem to have based their careers around bashing Kimball. In their desperation to present an alternative to Kimball's methodology and carve out their own niche, they've presented mostly incoherent, illogical and unusable ideas sometimes laced with anti-Kimball baggage. I get the feeling Inmon is kind of like James Martin was back in the 80's, churning out countless cookie-cutter style books of dubious quality.
I've designed a number of dimensional data warehouses and data marts that actually work years later using the Kimball approach, but honestly, every book I've read by Inmon and/or Imhoff has left me wondering who in the world actually uses their approach (if you can call it that) to build real-world data warehouses.
If you want to have a complete library and money is no object, by all means, read everyone's ideas on data warehousing and compare and contrast for yourself (I did - I must own fifty books on the subject - but I rely on only about 5-6 books in my day to day work as a DW architect - the rest are just taking up shelf space and reminding me how nice it is to be able to read reviews at places like Amazon before you buy). If money is an object and/or you are just starting out in the field and trying to learn the basics of DW design, do yourself a big favor and get the three excellent Kimball books (The Data Warehouse Toolkit, The Data Warehouse Lifecycle Toolkit and The Data Warehouse ETL Toolkit). The Adamson/Venerable book: Data Warehouse Design Solutions is a very useful adjunct for additional examples of real-world dimensional designs.Mastering Data Warehouse Design: Relational and Dimensional Techniques Overview
