What is MongoDB?

Relax. We'll talk through this in plain words — no textbook voice.

MongoDB is an open-source, document-oriented database that falls under the NoSQL category. Instead of tables and rows like traditional relational databases (SQL), MongoDB stores data as JSON-like documents in a format called BSON (Binary JSON).

javascript

// A sample document in a 'users' collection
{
  "_id": ObjectId("635f8e9e4a3b83d8a7c2c1b1"),
  "name": "Aung Aung",
  "age": 30,
  "courses": ["History", "Math"],
  "address": {
    "city": "Yangon",
    "street": "Main St"
  }
}
