System Analysis and Design
系统分析与设计课程讲授信息系统开发生命周期（SDLC）各阶段的方法与技术。主要内容包括需求获取与分析（访谈、问卷、用例）、结构化与面向对象分析方法、数据流图（DFD）、UML建模（用例图、类图、时序图）、系统设计（架构、数据库、界面）、敏捷方法与原型开发，以及实施与测试策略。培养学生从业务需求到系统方案的转化能力。
System Analysis and Design covers methods and techniques across the system development lifecycle (SDLC). Topics include requirements elicitation and analysis (interviews, surveys, use cases), structured and object-oriented analysis, data flow diagrams, UML modeling (use case, class, sequence diagrams), system design (architecture, database, interface), agile and prototyping, and implementation and testing strategies, enabling students to translate business needs into system solutions.
学生小组选定一个真实业务场景（如校园选课、社区物业），完成可行性研究、需求规格说明书、用例图与类图、数据流图与ER图、界面原型与系统架构设计。使用Visio或Draw.io绘制图表，使用Axure或Figma制作原型。最终提交完整分析设计文档并进行答辩评审。
Teams select a real business scenario (such as course registration or property management) and deliver a feasibility study, requirements specification, use case and class diagrams, DFD and ER diagrams, interface prototypes, and system architecture design. Diagrams use Visio or Draw.io; prototypes use Axure or Figma. Submit the full analysis and design document and present a defense.
