# MongoDB

MongoDB is an open source NoSQL database. MongoDB does not store data in tables according to a rigid schema. Instead, MongoDB stores data in documents that have a flexible schema or no schema at all.

Tonic Structural can work with MongoDB data that is either hosted on Atlas or is self-hosted.

You can also use the MongoDB data connector to connect to an Amazon DocumentDB database.

For MongoDB, **Database View** and **Table View** are replaced with **Collection View**.
