Purpose and Entry Point

This is a Java/Spring Boot course registration system. The application starts from src/main/java/com/example/Course/Registration/System/CourseRegistrationSystemApplication.java, which bootstraps the Spring application context and exposes the controller/repository/service layers.

HTTP/API Boundary

src/main/java/com/example/Course/Registration/System/controller/CourseController.java is the inbound API boundary. It receives course-related requests, delegates application behavior to the service layer, and returns results to callers. No UI or separate frontend is present in the repository.

Course Domain Model

src/main/java/com/example/Course/Registration/System/model/Course.java represents the core course entity/value model.

src/main/java/com/example/Course/Registration/System/model/CourseRegistry.java represents registration-oriented course state or associations. These models form the data exchanged between API, service, and persistence layers.

Application Service Layer

src/main/java/com/example/Course/Registration/System/service/CourseService.java centralizes course and registration business operations. It is the intended control-flow boundary between CourseController and persistence, preventing controllers from owning domain or database logic.

Persistence and Repository Boundary

src/main/java/com/example/Course/Registration/System/repository/CourseRepo.java provides persistence access for courses.

src/main/java/com/example/Course/Registration/System/repository/CourseRegRepo.java provides persistence access for course-registration records.

The primary flow is controller → service → repository → backing datastore, with repositories returning domain data back through the service to the controller.

Runtime and Infrastructure

The project is Maven-based (pom.xml, mvnw) and uses Spring Boot runtime conventions. Runtime configuration is located at src/main/resources/application.properties; this is the likely location for datasource, port, JPA, and external-service settings. The precise database and dependency set cannot be established from the supplied tree alone.

Architectural Boundaries

The package structure under src/main/java/com/example/Course/Registration/System/ separates transport (controller), business orchestration (service), domain state (model), and persistence (repository). Spring dependency injection connects these stages, while persistence details remain behind repository interfaces/classes.
