The Evolution Of The Soft Component System Model

Soft reusability is one of the most import issues, concerning to present soft engineering research, which is considered to be an approach to solve the Soft Crisis. Recently, Objected Oriented Component software technology become more and more popular and boom, lots of component architecture and technology have been promoted and developed, component based software development become more and more attached importance to.Article plunge a deep inside into the current component system and technology, given a Layer Directed Graphic model of component system (LDG model), present the definition. Given a complete review of the evolvement of the component system based on the LDG model, component developing, installing, updating and uninstalling are included. The service model of the component system is also being researched, as well as the way how service model contribute to the system evolvement.Validating was being given lastly. From the result of the example, we can conclude that the LDG model can nicely nourish the system evolvement, consequently enhance the soft reusability, support the incremental software development and make software more flexibility.
