2026-04-28 17:35:38 3b5c00 lisa Add C02 Use Case Diagram wiki page (5 PlantUML-rendered examples) Page covers actors, use cases, system boundary, and the four relationships (association, generalisation, include, extend), plus arrow-direction rules — the common UCD trap. Five focused PNGs pre-rendered from PlantUML and committed under sd/C02/Use Case Diagram/ (OtterWiki doesn't render PlantUML natively): - 01-base.png — simplest UCD (1 actor, 1 use case) - 02-multi-actor.png — Timetable system, 3 actors, 4 use cases - 03-generalisation.png — Administrator → Teacher → Student - 04-include.png — Edit User --«include»--> Load User - 05-extend.png — Display Help --«extend»--> Register User Blocks used: TIP intro, WARNING for arrow-direction trap, DANGER for common mistakes, SUCCESS for the draw-it order, INFO for the rubric stake. Four-question CYU with spoiler answers. Linked from C02-home under Analytical diagrams.
