UniversityLearn MongoDB from MongoDB

The database for
modern applications

MongoDB is a general purpose, document-based, distributed database built for modern application developers and for the cloud era. No database is more productive to use.

THE DOCUMENT MODEL

As a programmer, you think in objects. Now your database does too.

MongoDB is a document database, which means it stores data in JSON-like documents. We believe this is the most natural way to think about data, and is much more expressive and powerful than the traditional row/column model.

{
  "_id": "5cf0029caff5056591b0ce7d",
  "firstname": "Jane",
  "lastname": "Wu",
  "address": {
    "street": "1 Circle Rd",
    "city": "Los Angeles",
    "state": "CA",
    "zip": "90404"
  },
  "hobbies": ["surfing", "coding"]
}

Rich JSON Documents

• The most natural and productive way to work with data.

• Supports arrays and nested objects as values.

• Allows for flexible and dynamic schemas.

> db.users.find({ "address.zip" : "90404" })
{ "_id": "5cf0029caff5056591b0ce7d", "firstname": "Jane", "lastname": "Wu", "address":{}}
{ "_id": "507f1f77bcf86cd799439011", "firstname": "Jon", "lastname": "Davis", "address":{}}
{ "_id": "5349b4ddd2781d08c09890f3", "firstname": "Jim", "lastname": "White", "address":{}}
{ "_id": "5bf142459b72e12b2b1b2cd", "firstname": "Jeff", "lastname": "Taylor", "address":{}}
{ "_id": "5cf003283b23d04a40d5f88a", "firstname": "Jerry", "lastname": "Miller", "address":{}}
{ "_id": "5bf142459b72e12b2b1b2cd", "firstname": "Jai", "lastname": "Williams", "address":{}}
{ "_id": "5cf0036deaa1742dd225ea35", "firstname": "Jess", "lastname": "Johnson", "address":{}}
{ "_id": "54495ad94c934721ede76d90", "firstname": "Jill", "lastname": "Brown", "address":{}}
{ "_id": "566eb3c704c7b31facbb0007", "firstname": "Janet", "lastname": "Jones", "address":{}}
{ "_id": "5a999cc461d36489a27f2563", "firstname": "Jan", "lastname": "Smith", "address":{}}

Powerful query language

• Rich and expressive query language that allows you to filter and sort by any field, no matter how nested it may be within a document.

• Support for aggregations and other modern use-cases such as geo-based search, graph search, and text search.

• Queries are themselves JSON, and thus easily composable. No more concatenating strings to dynamically generate SQL queries.

session.start_transaction()
order = { line_items : [ { item : 5, quantity: 6 } ] }
db.orders.insertOne( order, session=session );
for x in order.line_items:
  db.inventory.update(
    { _id  : x.item } ,
    { $inc : { number : -1 * x.qty } },
    session=session
  )
session.commit_transaction()

All the power of a relational database, and more...

• Full ACID transactions.

• Support for joins in queries.

• Two types of relationships instead of one: reference and embedded.
