The only study to integrate a platform-driven decision framework with the model-driven architecture (MDA), this in-depth, practical guide explains how to combine three technology areas - MDA, ontologies, and software product lines - in order to integrate several platform-specific software products into a single MDA. Further exploring concepts such as knowledge-representation systems, artificial intelligence, and the 'semantic web', this complete resource reveals why these technologies are so highly relevant today and speculates on how they will impact future software development.
