5. System Architecture Interactive Fullstack Request Pipeline

Sequence Pipeline — End-to-End Transaction Flow
Admin / Client → Frontend (Next.js) Dispatches user action (Shift submit / Batch inbound / Filter request)
Frontend (Next.js) → Backend (Adonis.js / Go) Transmits authenticated REST payload with JWT & role permissions
Backend Logic → Database (SQL Server) Executes SQL Server Actions, checks column security & writes audit log
Database Engine → Cloud Host (Hostinger) Confirms ACID transaction & persists data across server volumes
Backend Server → Admin UI Dashboard Returns optimized JSON response & updates real-time visual status
