# kavindunimesh1030/easy-car-rental-service- architecture > Architecture diagram of the GitHub repository kavindunimesh1030/easy-car-rental-service-, generated by GitDiagram from its file tree, README and a sample of source files (last updated 2026-11-13). It is an AI-made overview: check details against the source. - Interactive diagram: https://gitdiagram.com/kavindunimesh1030/easy-car-rental-service- - Repository: https://github.com/kavindunimesh1030/easy-car-rental-service- ## Overview Easy Car Rental is a full-stack rental-management application. Its principal backend workflow accepts rental operations through MVC controllers, delegates business operations to services, and persists rental, customer, vehicle, and driver data through repositories. The frontend tree also shows customer rental, registration, and administration screens. The supplied excerpts and index support several backend call relationships, but do not show frontend-to-backend requests or the JPA database wiring, so those links are left unverified rather than inferred.
