 Introduction to MongoDB

MongoDB is a NoSQL, document-oriented database used for high-volume data storage. Instead of storing data in traditional rows and columns (as in relational databases), MongoDB stores data in flexible, JSON-like documents.

Each document can have a different structure, which makes MongoDB ideal for handling unstructured or semi-structured data, such as real-time analytics, content management, or IoT data.

Key Feature: MongoDB stores data in BSON (Binary JSON), which extends JSON by adding data types like date, int, long, etc.

 How MongoDB Works (Step-by-Step)

MongoDB stores data in a hierarchical format:

• Database ➜ Collections ➜ Documents

 1. Create a Database

js

CopyEdit

use myDatabase

 2. Create a Collection

js

CopyEdit

db.createCollection("students")

 3. Insert a Document

js

CopyEdit

db.students.insertOne({

  name: "Pallavi",

  course: "BCA",

  year: 3

})

 4. Query a Document

js

CopyEdit

db.students.find({ name: "Pallavi" })

 5. Update a Document

js

CopyEdit

db.students.updateOne(

  { name: "Pallavi" },

  { $set: { course: "MCA" } }

)

 6. Delete a Document

js

CopyEdit

db.students.deleteOne({ name: "Pallavi" }

 Syntax Overview with Example

Operation	Syntax	Description
Insert	db.collection.insertO..})	Add new document
Find	db.collection.find({...})	Search document
Update	db.collection.updateOne({...})	Modify document
Delete	db.collection.deleteOne({...})	Remove document

 

 Sample Document:

json

CopyEdit

{

  "_id": ObjectId("5f50c31b1c9d440000a1a2b3"),

  "name": "Alice",

  "email": "alice@example.com",

  "skills": ["MongoDB", "Node.js", "React"],

  "active": true

}

 Future Scope of MongoDB

MongoDB’s future is strong and growing with:

 1. Cloud Adoption

MongoDB Atlas (DBaaS) is booming in cloud-native applications.

 2. AI & Analytics

Used as backend storage in data-driven AI and analytics apps.

 3. Real-Time Applications

Chat apps, IoT systems, location-based services prefer MongoDB due to fast read-write and flexible schema.

 4. Integration with Big Data & ETL Pipelines

Compatible with Apache Spark, Kafka, and ETL tools like AWS Glue.
