## Overview

EpicParqueadero PRO is a Swing parking-management application backed by PostgreSQL. The documented operator workflow starts with login, opens an administrative navigation panel, then manages users, vehicles, rates, and parking entry/exit records; the operational screen also presents active vehicles and daily totals. UI-to-DAO links and database access are grounded in sampled source where available. Navigation and several screens are represented from README claims and the file tree; their unsampled internal wiring is not inferred.
