MongoDB is a document oriented database. Relational databases use tables and rows to store data, while MongoDB uses collections and JSON-like (BSON) documents. Let's see an example document of a Person: {
_id: ObjectId(5ef9ad76d0b5e4ad986c1552),
email: "theadamsacademy@gmail.com",
name: "Adam",
addresses: [
{
...
},
{
...
}
]
}
