MongoDB is a NoSQL, document-oriented database that stores data in flexible JSON-like documents instead of traditional SQL tables and rows.

For example, instead of a SQL table:

id	name	age
1	Rahul	25

MongoDB stores a document like:

{
  "_id": 1,
  "name": "Rahul",
  "age": 25
}

Key concepts

Database → contains collections
Collection → similar to a SQL table
Document → similar to a SQL row
Field → similar to a SQL column

MongoDB vs SQL

SQL	MongoDB
Database	Database
Table	Collection
Row	Document
Column	Field
Primary Key	`_id`
SQL queries	MongoDB queries

Why use MongoDB?

MongoDB is popular when you need:

Flexible data structures
Easy horizontal scaling
High-volume data handling
Fast development
Data that doesn't fit neatly into fixed tables

For example, an e-commerce product can have different attributes:

{
  "name": "Laptop",
  "price": 75000,
  "brand": "ABC",
  "specifications": {
    "ram": "16GB",
    "storage": "512GB SSD"
  }
}

The nested specifications can be stored directly inside the document, which is one of MongoDB's major advantages.
