# E-commerce on MongoDB

GrandNode is an open-source e-commerce platform built on **MongoDB** and ASP.NET Core. It has used a document database since its first release in 2016 - not as an add-on, but as the way it stores every product, order and page.

### Why a document database fits e-commerce

- **Products are documents.** A product with dozens of attributes, variants, prices per customer group, pictures and translations is stored as one document, not spread across many joined tables. Reading a product page is one query.
- **Flexible data.** Adding a field for a new kind of product does not need a schema migration across the whole catalog.
- **Scaling reads.** Replica sets spread reads across servers; a managed cluster such as MongoDB Atlas takes care of backups and failover.
- **Ready to run anywhere.** A local MongoDB, a Docker container or a cloud cluster all work - MongoDB 4.0 or newer.

### What it means for your store

- Large catalogs with many variants stay fast to browse and edit.
- Multi-store and marketplace setups share one database while keeping each store's data separate.
- Your data stays in your database - export it, report on it or connect it to other systems.

### And the trade-offs

A document database is a choice, not a free win. Your team will want to know MongoDB basics - indexes, backups and the query language - and reporting tools that expect SQL need a connector or an export. Our article [NoSQL vs SQL for e-commerce](https://grandnode.com/nosql-vs-sql-comparison-grandnode-nosql-ecommerce-software) goes into the details, and [why MongoDB](https://grandnode.com/why-mongodb-nosql-in-grandnode-ecommerce-solution) explains the reasons behind the choice.
