A database is a container for collections. Each application typically uses one or more databases within the MongoDB server.
Quick Answer
A database in MongoDB is a container for collections. One MongoDB server can host multiple databases. Each database has its own set of files on disk. You switch databases with "use dbname". Common practice: one database per application. Unlike SQL, creating a database just requires inserting data - no explicit CREATE DATABASE needed.
