MongoDB is a powerful and flexible NoSQL database designed for modern applications that need to handle large volumes of semi-structured or unstructured data. Let’s break it down clearly, with helpful video tutorials to guide you visually.

🧠 What Is MongoDB?

MongoDB is a document-oriented NoSQL database. Instead of storing data in tables like SQL databases, it stores data in JSON-like documents called BSON (Binary JSON). This makes it ideal for applications that require flexibility and scalability.

📺 What is MongoDB? explains how MongoDB handles JSON objects, geospatial queries, and deployment strategies, making it perfect for dynamic data models.

🗂️ Core Concepts in MongoDB

• Collection: A group of MongoDB documents (like a table).
• Document: A single record, stored in BSON format.
• Field: A key-value pair inside a document.

📺 MongoDB databases explained shows how to use MongoDB Shell and Compass to create collections and manage databases interactively.

🧩 Example Document

{
  "_id": "12345",
  "name": "Alice",
  "email": "alice@example.com",
  "preferences": {
    "theme": "dark",
    "notifications": true
  },
  "hobbies": ["reading", "cycling"]
}

This structure is flexible—you can add or remove fields without altering a schema.

🚀 Features of MongoDB

• Schema-less: No rigid structure; documents can vary.
• Scalable: Uses horizontal scaling via sharding.
• High Availability: Built-in replication and failover.
• Fast Reads/Writes: Optimized for performance.
• Aggregation Framework: Powerful data processing (like SQL’s GROUP BY).
