In programming, when working with a database, you need a language for querying and manipulating data. The most common language is SQL (structured query language).
MongoDB is a NoSQl (not only SQL) database. It is a non-relational database; it is a document-based database. This means data is stored in JSON format.
In MongoDB, data is called a record or a document. The documents have a key-value structure and look like JSON. Example:
{"name": "Lil baby"}
All documents have a unique id. Documents are stored in collections, and a collection can hold many records. You need to use the collection name in your queries such as insert, retrieve and delete.
Commands
show dbs : This will show all the database on your server.
use testDB : This will create a new database.
show collections : This will show all the collections in a database.
db.dropDatabase() : This will delete a database.
