This document provides an overview of MongoDB, a document database. It discusses MongoDB's schema-free data model and scalability advantages over relational databases. It also covers installing and using MongoDB with PHP, including connecting to MongoDB, performing CRUD operations, and translating common SQL queries to MongoDB's query language. The document concludes by inviting the reader to try out MongoDB and links to download and PHP driver documentation pages.

6. NoSQL vs RDBMS
NoSQL RDBMS
● Schema-free ● Relational schema
● Scalable reads
● Scalable writes/reads
● Custom high-availability
● Auto high-availability ● Flexible queries
● Limited queries ● Consistency
● Eventual Consistency ● ACID
● BASE

10. Installing MongoDB server
ubuntu way
● sudo apt-key adv --keyserver keyserver.ubuntu.com --recv 7F0CEB10
● deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist
10gen
● sudo apt-get update
● sudo apt-get install mongodb-10gen
windows (shame on you!) way
● Download - http://mongodb.org/downloads
● Unzip
● Create a data directory
● Run and connect to the server
p.s.: 32bit is limited to 2.5gb size limit.

20. PHP and MongoDB
Installation
or `sudo pecl install mongo`
To load the extension, add a line in php.ini:
`extension=mongo.so` # of course without quote

23. CRUD

24. SQL to MongoDB
CREATE TABLE USERS (a Number, b Number) $db->users->insert(array("a" => 1, "b" => 1));
INSERT INTO USERS VALUES(1,1) $db->users->find(array(), array("a" => 1, "b" => 1));
SELECT a,b FROM users $db->users->find(array("age" => 33));
SELECT * FROM users WHERE age=33 $db->users->find(array("age" => 33), array("a" => 1,
SELECT a,b FROM users WHERE age=33 "b" => 1));
SELECT a,b FROM users WHERE age=33 ORDER $db->users->find(array("age" => 33), array("a" => 1,
BY name "b" => 1))->sort(array("name" => 1));
SELECT * FROM users WHERE age>33 $db->users->find(array("age" => array('$gt' => 33)));
SELECT * FROM users WHERE age<33 $db->users->find(array("age" => array('$lt' => 33)));
SELECT * FROM users WHERE name LIKE "%Joe%" $db->users->find(array("name" => new MongoRegex
("/Joe/")));
SELECT * FROM users WHERE name LIKE "Joe%"
$db->users->find(array("name" => new MongoRegex
SELECT * FROM users WHERE age>33 AND
("/^Joe/")));
age<=40
$db->users->find(array("age" => array('$gt' => 33,
SELECT * FROM users ORDER BY name DESC
'$lte' => 40)));
$db->users->find()->sort(array("name" => -1));
