Design patterns are immensely powerful, but to build large-scale robust systems, you need more. Pattern-Oriented Analysis and Design introduces a methodology for 'composing' proven design patterns into reliable, robust large-scale software systems. Using POAD, you can quickly build systems that are far more robust, scalable, and maintainable-using UML class diagrams as your building blocks. POAD: What it is, how it works, and what problems it solves Structural and behavioral approaches to design pattern composition Design models and UML techniques for pattern composition POAD processes: in depth coverage of analysis, design, and design refinement A systematic process to compose design patterns 4 chapter-length case studies: feedback control, customer behavior simulation, digital content processing, and distributed medical informatics Building on POAD: advanced trends and research Pattern-Oriented Analysis and Design takes design patterns to the next level. Whether you're an architect, designer, developer, or manager, it will help you build better software systems faster. A practical methodology to compose and deploy design patterns in creating better systems and developing better software applications. It shows how to exploit the significant power of design patters and make better design decisions with the proven POAD methodology. Case studies are included.
