This is a good introduction to the Rational Rose tool and the Rational method of developing software. A reader should have a prior introduction to UML even though nothing advanced is presented here. What the book does best is build your confidence for tackling a large scale project using UML and Rational Rose to develop the object model. While the book includes some step by step instructions and tracks a development project from beginning to end it is not a definitive guide. The review is very broad brush. Terry Quatrani writes very clearly and for the most part fulfills the objectives that she sets out. There were a couple of points that I could not follow even rereading multiple times and I found myself wanting just a little more explanation of illustrations.
