Component-based software development aims to reduce costs of developing large distributed systems through programming by assembly rather than development. It focuses expertise on domain problems and improves quality. The document discusses component-based development tools and processes including component libraries, visual design tools, deployment tools and validation tools. It also covers component execution models using CORBA and containers, which provide separation of concerns between business and technical code.
