CASE ANALYSIS
Scenario
An expo judging platform must track expos, categories, projects, teams, judges, assignments, scores, awards, and winners.
Key decisions
- Surrogate keys for assignments and scores simplify references while preserving judge-project links.
- Winner entity links Awards to Projects and supports multiple ranks per award.
When to reuse this
Use when modeling multi-category expos where judges score projects and organizers assign awards to winning projects.
