## Overview

This is an order-management system with a Next.js interface and an Express/Mongoose backend. Users browse products, manage a cart, place and track orders; administrators and support staff manage users, products, orders, and inventory adjustments. Backend routes apply role and input checks before controllers perform domain operations. The README documents Redis caching and Socket.IO updates for stock and order status. Some frontend-to-API wiring and the event implementation are not shown, so those links are omitted or marked unverified.

Main entry points: [`Backend/src/routes.js`](https://github.com/yeyintthway13/ordermanagementsystem/blob/main/Backend/src/routes.js) (API mounts), [`Backend/src/controllers/base-controllers.js`](https://github.com/yeyintthway13/ordermanagementsystem/blob/main/Backend/src/controllers/base-controllers.js) (Shared CRUD / queries), [`Backend/src/routers/order-routers.js`](https://github.com/yeyintthway13/ordermanagementsystem/blob/main/Backend/src/routers/order-routers.js) (Order routes), [`Backend/src/routers/inventory-adjustment-routers.js`](https://github.com/yeyintthway13/ordermanagementsystem/blob/main/Backend/src/routers/inventory-adjustment-routers.js) (Inventory routes)
