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"]}
