I expected to find some examples how all that look and work in real life. This, however, is not a book that I needed. It gives you some background in OO modeling that I did not like and actually did not need at all. I also suspect that somebody without previous OO knowledge might be confused. For example, on page 41, Properties, it is written: "A property is a value used to denote a characteristic of a class; it can be thought of as a pair of functions, one to set the property value and one to return the property value." Property access methods are confused with a property itself !
XML part is very short and general so I still have to go somewhere else to figure out how to implement XML part. Almost the same can be said about DEN - CIM relation.
The authors are obviously knowledgeable in the areas of OOA/OOD, Patterns and Enterprise management. I do not like their presentation but it may happen that I am not a part of their 'target group' for which they wrote the book. That is why I gave the book 3 stars. As far as I am concerned, I have to go to DMTF web site to learn hard way from documents. This book did not help me to do my job more efficiently.
