Both advanced and practical
Rated out of 5 stars, June 12th, 2009
A belated but welcome sequel to vol.s 1-2 in the series. The book is one-of-its kind, advanced (in parts: very!), dry (in parts: very!) and will probably confuse a novice modeler. On the other hand it is practical and takes relational modeling to a new level for experienced modelers. The key point so well explained and exemplified is that there are different levels of modeling of the same subject - each with a proper purpose and use. There is never one true and correct model, a data model is after all 'a model', a representation of something, not the thing itself. The true modeling professional must know when to choose one or the other model type, and when and how to switch between them. After all, data modeling may be an art and it may be a craft, but it is definitely not an exact science (though a great many other data modeling books may leave that impression).
