Full Potential of Mda, Which Allows for Models at Multiple

layers of abstraction, and which has a meta-modelling and model interchange framework enabling the use of multiple modelling languages, is only hinted at. That said, the author does provide a catalogue of patterns-based transformations that is very useful in the preparation of a Java implementation skeleton from a UML design. However, some sections make one wonder whether the words ‘Advanced Systems Design’ in the title are justified. There is a superficial introduction of methodology, while no discussion is given to separation of concerns or information hiding, and only a cursory mention is made of three-tiered architectures. The designs shown given range across GUI, OO implementation and databases without the role of MDA in separating these viewpoints being discussed. An objectrelational mapping is described, but it avoids all the difficult issues related to the mapping of subtypes. Chapters seven and eight diverge from the stated subject matter of the book by introducing a grab-bag of web and mobile technology discussions. In particular, J2EE is given shallow treatment, apparently due to lack of space consumed by discussions of .net, Bluetooth, and semantic web, among other topics, which adds little to the main thrust of the book. In summary, the book is a very good introduction to the use of UMLwithin a limitedMDA framework. It provides an emphasis on completeness using constraints, which is vital toMDA,where the more semantics a model contains, the more completely designs can be transformed into implementations. The rules highlighted in the text, the catalogue of transformations and the guidelines formodularization alonemake this book valuable. The book’s digressions into non-core topics are a shame if only because the space could have been used to better expand on MDA, J2EE and other core areas.
