NoSQL and MongoDB

MongoDB stores data as flexible JSON-like documents instead of tables.

📖 Key ideas

  1. MongoDB is a NoSQL document database.
  2. Data is stored as BSON documents inside collections.
  3. Documents in one collection can have different fields.
  4. Good for flexible, fast-changing data and JSON-heavy apps.
  5. MongoDB Atlas is the managed cloud service.
💡 Real-life example: A MongoDB collection is a file folder where each paper (document) can have its own layout.
DocumentOne JSON-like record
