  1. INFS 6225Object Oriented Systems Analysis & Design Chapter 4: Functional Modeling

  2. Use-Case • Illustrates the activities performed by the users of a system • Depict the Users’ view of a system • Are logical models • Are technology-independent • Can be used to describe current (As Is) or future (To Be) system

  3. Use-Case: 2 Parts • Use-Case Descriptions – Written, less formal documents that describe the functions of a system • Use-Case Diagram – Formal, graphical representation of the functions of a system Use-Case Descriptions are created first; Use-Case Diagrams are then created from Use-Case Descriptions

  4. Use-Case Description Use Case Name: ID: Importance Level: Primary Actor: Use Case Type: Stakeholders and Interests: Brief Description: Trigger: Relationships: (Association, Include, Extend, Generalization) Normal Flow of Events: Subflows: Alternate/Exceptional Flows:
