Integration is one of the most critical technical challenges in software today, as well as a difficult topic to generalize because of the many things affecting it — the technologies involved, the timeframe, the number and types of user communities requiring access, regulatory requirements, and so on.  Fundamentals of Software Integration provides an overview of the evolution of software technology, with a particular emphasis on long-standing problems that remain unsolved.  It then uses this background as a basis for presenting an abstract model of the software application and its environment, along with a methodology for how to use this model to develop an integration strategy that meets both short and long-term needs of the organization.  Hammer and Timmerman's accessible writing style and strategic exercises help students recognize similarities in the integration challenges faced across technologies.
