I've read more than my share of technical texts over the years. With a few exceptions, most are dry, difficult to understand and cover too much material without developing any topic particularly well.
Leon Starr's book "Executable UML: How to Build Class Models" is refreshingly different. Not only is it written in a uniquely engaging style, but it does a fantastic job of developing the concepts that go into Executable UML class modeling.
Furthermore, his introduction "What is Executable UML?" is the best concise overview of the topic I have *ever* read. In under 25 pages, Leon hits every major point of discussion in Executable UML in enough detail to provide real value for the reader. Although it's well worth reading for anyone who's interested in Executable UML modeling, I would especially recommend this chapter to anyone who is *new* to Executable UML, and wants to understand what all the fuss is about.
Leon's approach to the subsequent chapters on class modeling doesn't bog down the book with a complicated discussion of an abstract (and potentially complicated) topic. His discussion is clear, concise, with frequent use of examples to hammer home his points.
He always provides a brief scenario before he launches into a modeling example, giving a excellent context for why he used certain modeling techniques. For beginners in Executable UML, this is an excellent way to get into the mindset of modeling. More experienced readers can also benefit a great deal from the best practices discussed.
Another myth about technical texts is that good content = dry read. Not so! Leon's book is *very* entertaining. This has got to be one of the most pleasant technical reads out there. Interestingly enough, when I turned the final page, not only had I enjoyed the journey, but I found that I *really* understood the topic.
More books should be written like this! "Executable UML: How to Build Class Models" is the exception that *should* become the rule.
