Data Structure

MongoDB is a document-oriented NoSQL (non-relational) database. Its data structure consists of fields and values like JSON objects. Below is an example:

{
  name:"John Smith",
  sex:"Male",
  age:25,
  status:"A",
  groups:["news","sports"]
}

Storage Structure

MongoDB's storage structure consists of the following three units:

• Document: It is the most basic unit in MongoDB and composed of BSON key-value pairs.

  {name:"Jane Smith",sex:"Female",age:25,status:"A"}
  

• Collection: A MongoDB collection can contain multiple documents. For example, you can insert documents with different data structures into the same collection.

  {name:"Jane Smith",sex:"Female",age:25,status:"A"}
  {name:"Jane Smith",sex:"Female",age:25,status:"A"}
  {name:"Harry Smith",sex:"Male",age:26,status:"A",groups:["news","sports"]}
  

• Database: A MongoDB database can contain multiple collections, and you can create multiple databases.
