## Overview

E-Commerce Analytics is a MERN dashboard for sales KPIs, customer demographics, product rankings, data entry, and CSV reports. Users view analytics or enter product, customer, and order records; the React app fetches analytics through its API client, while Express routes compute MongoDB aggregations and persist records through Mongoose models. The dashboard presents those results as cards, charts, and a table; reports reuse fetched results for display and CSV downloads. The README documents the API-to-database architecture and report capabilities; unsampled integration details are not inferred.

Main entry points: [`frontend/src/App.js`](https://github.com/sainath9391/ecommerce-dashboard/blob/main/frontend/src/App.js) (App coordinator), [`backend/routes/analytics.js`](https://github.com/sainath9391/ecommerce-dashboard/blob/main/backend/routes/analytics.js) (Analytics routes), [`backend/routes/data.js`](https://github.com/sainath9391/ecommerce-dashboard/blob/main/backend/routes/data.js) (Data routes), [`frontend/src/services/api.js`](https://github.com/sainath9391/ecommerce-dashboard/blob/main/frontend/src/services/api.js) (API client)
