【摘要】 用例是获取需求的主要工具,用例模型成了与用户交流的手段。装配式软件是一种能提高软件适应性和生命力的系统,它是建立在基于组件的工程基础之上,以便系统维护时可以按组件装配、拆卸和替换。讨论了用例模型中的用例如何与组件建立映射关系,并给出装配式软件开发的具体过程。更多还原

【Abstract】 Use cases are primary tools of eliciting requirements, and use case models become the method of communication with customers in UML and object-oriented methodologies. The assembly-like software system is presented, which can improve the capabilities and add life of software based on component-based software engineering, and it is easy to assemble, disassemble and replace according to components during maintenance. How to constitute the relations between components and use cases in its models is discussed, and the process of development of assembly-like software systems is given.更多还原
