MongoDB is one of the most popular NO-SQL databases. The word is derived from humongous.
It's a relatively new breed of database that has no concepts of tables, joins, foreign keys, transactions etc.
It is an open-source document-oriented database developed by MongoDB inc. in 2009.
So MongoDB doesn't use table, row, column format to store data, rather it uses a storage format called BSON which is similar to JSON.
MongoDB is used for high volume data storage.
A simple MongoDB structure :
<pre><code class="lang-bash">{
 name:'Jack',
 age:22,
 city:'brooklyn'
}
</code></pre>

<h3 id="database">Database</h3>
It is a physical container for data. We can store multiple databases on a single MongoDB server.
<h3 id="document">Document</h3>
A set of key-value pairs is known as Document.
Basically, a record is called a document that is associated with a dynamic schema. The benefit of having a dynamic schema is that a document in a single collection does not have to possess the same structure or field.
<h3 id="collection">Collection</h3>
This is a grouping of MongoDB documents.
Consider the collection as Table in RDBMS. The entire collection exists within a single database.
There is no schema when it's come to a collection.

## Key components of MongoDB Architecture

### Database

It is a physical container for data. We can store multiple databases on a single MongoDB server.

### Document

A set of key-value pairs is known as **Document**.

Basically, a record is called a document that is associated with a dynamic schema. The benefit of having a dynamic schema is that a document in a single collection does not have to possess the same structure or field.

### Collection

This is a grouping of MongoDB documents.

Consider the collection as Table in RDBMS. The entire collection exists within a single database.

There is no schema when it's come to a collection.
