用例模型--SSD

用例模型-SSD ●细化阶段 ●系统顺序图 ●SSD和用例之间的对应关系 ●系统事件和操作的命名 ●SSD和UP

用例模型--SSD 细化阶段 系统顺序图 SSD和用例之间的对应关系 系统事件和操作的命名 SSD和UP

细化阶段 细化阶段开始OOAD,应用UML, patterns,and architecture 多数的需求被发现和稳定下来 主要的风险被缓解 ●实现和验证核心体系结构元素

细化阶段 细化阶段开始OOA/D, 应用UML, patterns, and architecture. ⚫ 多数的需求被发现和稳定下来 ⚫ 主要的风险被缓解 ⚫ 实现和验证核心体系结构元素

用例模型--SSD 细化阶段 系统顺序图 SSD和用例之间的对应关系 系统事件和操作的命名 SSD和UP

系统顺序图 ●顺序图显示参与者和系统之间的事件 创建系统顺序图是调査要建造什么系统的工作的 部分 在进行逻辑设计之前以黑箱调查系统的行为 系统行为是描述系统做什么,而不是怎么做 系统顺序图 ●用例 系统合约

系统顺序图 ⚫ 顺序图显示参与者和系统之间的事件 ⚫ 创建系统顺序图是调查要建造什么系统的工作的 一部分 ⚫ 在进行逻辑设计之前以黑箱调查系统的行为 ⚫ 系统行为是描述系统做什么，而不是怎么做 ⚫ 系统顺序图 ⚫ 用例 ⚫ 系统合约
