## Overview

This is a JavaFX desktop system for managing sports-complex operations through department-specific screens backed by JDBC/MySQL. The primary user workflow is login, role-based dispatch to a department workspace, and then managing or viewing that department’s records. Its domain areas include registration, finance, maintenance, inventory, emergencies, attendance, coaching, and manager oversight. The sampled controllers show direct database access for several workflows; other capabilities and department responsibilities are retained from the README, but their internal wiring is not inferred.

Main entry points: [`Sports Complex/src/sports/complex/login/LoginController.java`](https://github.com/tchawla827/sports-tournament-management-system/blob/master/Sports%20Complex/src/sports/complex/login/LoginController.java) (Login), [`Sports Complex/src/Database/DbQuery.java`](https://github.com/tchawla827/sports-tournament-management-system/blob/master/Sports%20Complex/src/Database/DbQuery.java) (JDBC queries), [`Sports Complex/src/sports/complex/finance/FinanceController.java`](https://github.com/tchawla827/sports-tournament-management-system/blob/master/Sports%20Complex/src/sports/complex/finance/FinanceController.java) (Finance workspace), [`Sports Complex/src/sports/complex/SportsComplex.java`](https://github.com/tchawla827/sports-tournament-management-system/blob/master/Sports%20Complex/src/sports/complex/SportsComplex.java) (Desktop entry)
