## Overview

This is a full-stack user and product management application. A person uses the React interface to view records and create, edit, or delete them; the interface sends requests to the Express API, which uses Mongoose models to access MongoDB. User and product CRUD are distinct domain branches, while the client keeps the two collections and their form state together in one component. The client excerpt is partial, so the graph shows documented capabilities where supported but does not infer additional UI modules or routes.

Main entry points: [`3ND/client/src/App.js`](https://github.com/damian591/full-stack-user-and-product-management-system/blob/main/3ND/client/src/App.js) (Management UI), [`3ND/server/index.js`](https://github.com/damian591/full-stack-user-and-product-management-system/blob/main/3ND/server/index.js) (User CRUD API), [`3ND/server/models/Users.js`](https://github.com/damian591/full-stack-user-and-product-management-system/blob/main/3ND/server/models/Users.js) (User model), [`3ND/server/models/Products.js`](https://github.com/damian591/full-stack-user-and-product-management-system/blob/main/3ND/server/models/Products.js) (Product model)
