This document introduces MongoDB, a NoSQL database that stores data in flexible, JSON-like documents rather than rigid tables. It notes that MongoDB is scalable, supports many programming languages, is free to use, and easy to install. The document provides instructions on installing MongoDB and the PHP driver and includes examples of basic usage from the terminal.

9. MongoDB Installation
1. Add 10gen package to source.list
sudo gedit /etc/apt/sources.list
Add : deb
http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist
10gen
2. sudo apt-get update
3. 10gen package required GPG key, import it :
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv
7F0CEB10
4. sudo apt-get install mongodb-10gen ---- Done
5. Test : tito@tito:~$ mongo
MongoDB shell version: 2.0.6
connecting to: test

10. PHP Driver Installation
Check that the PEAR and PECL are working with the following
commands:
$ PECL version
If not found, install it to following commands:
sudo apt-get install php-pear
Then, sudo pecl install mongo
Add the following line to your php.ini file:
sudo gedit /etc/php5/apache2/php.ini
extension=mongo.so
Then Restart Web Server
/etc/init.d/apache2 restart ---- DONE

11. Using from Terminal

$ mongo

> show dbs – Get list of all databases

> use microfin – creating DB

> db.users.insert( { _id : "alex", name: { first:"Alex",
last:"Benisson" }, karma : 1.0 } )

> db.users.insert( { name: { first:"Kamal", last:"Khan" }, address
: '33,Dhaka' } )

> show collections – Get collections list

> db.users.find()
