How nguyen-anh-hao/hhkt-ex-tkpm works
<explanation>
1. Identify the project type and purpose
- This is a full‑stack student‑management system comprising:
• A Next.js (React) single‑page application for class, course, student, registration, transcript management.
• A Java Spring Boot REST API backend implementing layered MVC (controllers, services, repositories) with import/export, validation, and database persistence.
• A relational database (seeded via Docker) storing domain entities (Student, Course, ClassRegistration, etc.).
2. Analyze the file structure
- Top‑level directories:
• client/: Next.js frontend
• server/: Spring Boot backend + Docker Compose + SQL scripts
• docs/: project guides
- Frontend pattern:
• src/app: route directories (class‑management, course‑management, …) each with page.tsx, components, actions
• src/libs: API wrappers, React Query hooks, service facades, Zustand stores, validators, utils
- Backend pattern:
• src/main/java/org/example/backend/config: CORS, Jackson, OpenAPI, status‑rules configuration
• controller → service (including import/export factories) → repository → domain
• dto (request/response) + mappers to translate domain ↔ DTO
• resources: application.yml, SQL seeds, import/export config
3. Examine the README for additional insights
- The README describes how to run the client and server, highlights Swagger UI, and shows a database ER diagram.
- Use cases: Manage students, courses, classes, registrations, reference data, status‑rules, transcripts.
4. How to create an accurate system design diagram
a. Main components
• Web Browser / End‑user
• Frontend (Next.js App)
– Pages & React components
– API clients / services / hooks
• Backend (Spring Boot App)
– Controllers (REST API endpoints)
– Service Layer (business logic, import/export factories)
– Repository Layer (Spring Data JPA)
– Domain Models, DTOs, Mappers, Validators
• Database (Docker‑hosted RDBMS)
• External services/tools (Swagger UI, file storage for Document uploads, PDF exporter)
b. Relationships & interactions
• Browser → HTTP(S) → Next.js (client rendering, React routing)
• Frontend services (libs/api/*.ts) → HTTP → Spring Boot controllers
• Controller → inject → Service → calls → Repository → SQL → Database
• Import/Export service factory selects CSV, Excel, JSON, XML, PDF implementations
• Validation annotations & custom validators enforce business rules on requests
c. Architectural patterns/design principles
• Frontend: Component‑based UI, custom hooks for data fetching (React Query), separation of concerns (actions, services, stores)
• Backend: Layered architecture (Controller → Service → Repository), DTO/Entity mapping, Factory pattern for import/export
• Configuration‑driven (application.yml, data_import.json/xml, student‑status‑rules.json)
• Use of Dependency Injection (Spring) and RESTful principles
d. Key technologies/frameworks
• Frontend: Next.js, React, TypeScript, React Query, Zustand, ESLint
• Backend: Spring Boot, Spring Data JPA, Lombok (for Auditable), Jackson, OpenAPI/Swagger, Maven, Docker
• Database: PostgreSQL/MySQL (via docker-compose), SQL seed scripts
5. Tailoring guidelines for a full‑stack application
- Visually separate Frontend and Backend tiers.
- On the Frontend side, show:
• Pages (routes) → Components → Services → API modules → HTTP client
- On the Backend side, show:
• Controllers → Service Layer → Repository Layer → Database
• Import/Export Factory and Validator modules as side‑branches of the Service Layer
- Indicate configuration sources (application.yml, JSON/XML rules) feeding into Services/Factories.
6. Diagram notation and details
- Use clear component boxes with labels (e.g., “ClassManagementPage”, “CourseServiceImpl”, “IStudentRepository”)
- Draw directional arrows showing data flow:
• Solid arrows for request paths (Browser → Frontend → Backend → DB)
• Dashed arrows for configuration or factory selection
- Color code by layer/type:
• Blue: Frontend components
• Green: Backend tiers (controllers, services, repositories)
• Orange: Database
• Grey: External/config files, Swagger UI, file storage
- Use distinctive shapes:
• Rectangles for modules/services
• Cylinders for Database
• Document icons for config files
7. Essential architectural elements to capture
- All frontend feature modules (class‑management, student‑management, etc.)
- API client layer (libs/api) and React Query hooks (libs/hooks)
- Backend import/export & validation factories
- DTO ↔ Entity mapping layer
- Database schema (seed scripts)
- Docker‑Compose orchestration for DB
By following these steps and using the above guidelines, you can draft a detailed, accurate system design diagram that clearly shows the full‑stack student‑management system’s components, their relationships, and the technologies that bind them together. Ensure every major module is represented, flows are clearly indicated, and color/shape conventions separate concern boundaries.
