文章探讨了基于UML进行面向对象的系统分析及设计方法，包括静态建模和动态建模；提出了一种实用的基于UML的需求分析及其建模方法，以活动图模型来表达业务模型，以概念层的对象图、状态图及交互图模型表达系统的结构逻辑及行为逻辑，以应用例图表达系统需求；讨论了需求分析及其建模的过程概念，并以高校开放式学籍管理系统的开发作为案例示范

Interaction diagrams are used to model the dynamic aspects of a software system They help you to visualize how the system runs. An interaction diagram is often built from a use case and a class diagram. —The objective is to show how a set of objects accomplish the required interactions with an actor

10.1 Basic definitions A failure is an unacceptable behaviour exhibited by a system —The frequency of failures measures the reliability —An important design objective is to achieve a very low failure rate and hence high reliability. —A failure can result from a violation of an explicit or implicit requirement

Definition: Design is a problem-solving process whose objective is to find and describe a way: —To implement the system’s functional requirements... —While respecting the constraints imposed by the non-functional requirements... - including the budget
