## Overview

Mohaeng is a Spring backend for an integrated travel platform: members can generate personalized itineraries, discover and book flights, lodging, and tours, then use payments and travel-community features. The README documents separate JSP member and React admin clients, hybrid session/JWT authentication, and an Oracle/MyBatis persistence layer. The graph groups the main product domains and preserves documented AI, external-data, and real-time-chat capabilities. Sampled sources confirm selected service-to-mapper calls; unsampled domain wiring is represented only where the README documents it.
