MongoDB is a free and open-source cross-platform document orient database program. Unlike classic SQL databases, MongoDB uses BSON (like JSON) to store data. Meteor was designed to use MongoDB for database storage and this topic explains how to implement MongoDB storage into Meteor applications.
Authentication is the process of verifying the identity of a client. When access control, i.e. authorization, is enabled, MongoDB requires all clients to authenticate themselves in order to determine their access.
MongoDB supports a number of authentication mechanisms that clients can use to verify their identity. These mechanisms allow MongoDB to integrate into your existing authentication system.
MongoDB is one of the most popular NoSQL databases, thanks to the help of the MEAN stack. Interfacing with a Mongo database from an Express app is quick and easy, once you understand the kinda-wonky query syntax. We'll use Mongoose to help us out.
