MongoDB

MongoDB

MongoDB is an open-source document database and leading NOSQL database. MongoDB is written in C++. This tutorial will give you great understanding on MONGODB concepts needed to create and deploy a highly scalable and performance-oriented database.

NOSQL DB

Data Store in JSON format like (BSON). Horizontal Scalable Key Value Pair :

{
    name : "prakash",
    age : 20,
    degree : "BCA"
}

Mongo, MongoD, Mongo Compass, Mongo Atlas..

Mongo

It is the Command-line shell that connects to a specific instance of MongoD.

MongoD

It is the Mongo Daemon, basically the host process for the database, run it in the background.

Mongo Compass

It is a powerful GUI for querying, aggregating and analyzing your MongoDB data in a visual enviroment.

Mongo Atlas

It is a fully-managed cloud database that handles all the complexity of deploying, managing and healing your deployments on the cloud server provider of your choice (AWS, AZURE).

JSON (JAVASCRIPT OBJECT NOTATION)

It's a light weight format for storing and transporting data, JSON is often used when data is sent from a server to web page.

It is a common mistake to call a JSON object literal "a JSON object".

JSON cannot be an object. JSON is a string format.

The data is only JSON when it is in a string format. When it is converted to a JavaScript variable, it becomes a JavaScript object.

{
   "Course": [
      {
         "id":"033",
         "language": "JavaScript"
      },	
      {
         "id":"034",
         "language": "MongoDB"
      }
   ]
}
