Have you ever read a book where halfway through it, your expectations begin dwindle because the author either did not cover the topic or promises to cover it in more detail in later chapters, but never does? If you ever feel this way about a book, then this is the perfect examples of those types of books.After reading the synopsis and browsing some of the crude methods that I can assimulate with when I was performing requirements modeling, I thought this book might come in handy. After close scrutiny, I was very disappointed by the authors lack of knowledge in UML. A lot of what was presented was very superficial, and the explanations were lacking in terms of it presentation of each of the models in UML. I should have stuck with the three authors (Jacobson, Booch, and Rumbaugh) who were the original designers of UML.
