Aspect-oriented software development is emerging as a proven approach for allowing the separate expression of multiple concerns, along with "weaving" technologies for knitting together these separate expressions into coherent systems. In other words, it offers great promise as an approach to simplifying the development of complex modern software systems. Many expert observers view AOSD as a worthwhile successor to the popular object-oriented paradigm that is prevalent in contemporary software engineering. In this new book, AOSD experts Clarke and Baniassad apply proven theory to the practical realm of real-world development. The result is an applicable and easy-to-digest methodology for simplifying and optimizing the development of thoroughly modern software systems.
