MongoDB Tutorial
MongoDB is a document database. It stores data in a type of JSON format called BSON.
If you are unfamiliar with JSON, check out our JSON tutorial.
A record in MongoDB is a document, which is a data structure composed of key value pairs similar to the structure of JSON objects.
A MongoDB Document
Records in a MongoDB database are called documents, and the field values may include numbers, strings, booleans, arrays, or even nested documents.
Example Document
{
title: "Post Title 1",
body: "Body of post.",
category: "News",
likes: 1,
tags: ["news", "events"],
date: Date()
}
