Interview Prompt
Design a data model for a sports tournament platform. The platform tracks multiple leagues, each with multiple teams. Players belong to teams, but can also represent national teams in separate competitions. Each match has two teams, takes place at a stadium, and produces per-player and per-team stats. Analytics need cumulative player scores across all matches in a tournament.
Summary
A player can belong to many teams. The schema must agree.
