AST Sports Association use-case and class diagram models a comprehensive web platform serving members, coaches, administrators, and the national federation. The system enables public visitors to browse news and club info, while licensed members manage convocations, availability, equipment orders, and license renewals with integrated banking transactions. Administrative actors—secretaries, presidents, and automated processes—handle member onboarding, event creation, content moderation, and seasonal closure, with all entities (Person, Member, Team, Convocation, License, News, Equipment, Transaction) interconnected through a unified domain model. This architecture demonstrates how to structure a multi-role sports management system balancing public access, member self-service, and administrative governance. Fork and customize this diagram on Diagrams.so to adapt it for your federation's specific workflows and role hierarchies.
