Object technology and object-oriented systems development are the latest stage of systems development evolution. This comprehensive guidebook illustrates that object-oriented design is an evolution, rather than a revolution, in software engineering. It reviews the principles of conventional software design as the context for design objects; defines the specific components of on object-oriented design within that context; and provides a layered model and a corresponding methodology for developing and designing large scale object-oriented systems in a way that eases the transition to object-oriented techniques.
