software. – Resulted from the convergence of notations from three
leading object-oriented methods:
• OMT (James Rumbaugh) • OOSE (Ivar Jacobson) • Booch (Grady Booch)
between objects of the system. • Statechart diagrams(狀態圖)
– Describe the dynamic behavior of an individual object as a finite state
machine. • Activity diagrams(活動圖)

System Analysis and Design 系統分析與設計
物件導向式分析設計 - 使用 UML 使用案例圖
What is UML?
• UML (Unified Modeling Language)
– 統一塑模語言 – An emerging standard for modeling object-oriented

UML First Pass
• Use case diagrams(使用案例圖)
– 描述使用者所見之系統的功能性行為.
– Model the dynamic behavior of a system, in particular the workflow,
i.e. a flowchart.
使用 UML 來產生視覺化模型
