Installing MongoDB 2.0.3 on Ubuntu 10.04


I tried following the following wiki:http://www.mongodb.org/display/DOCS/Ubuntu+and+Debian+packages

Didn’t workout so i decided to have my own triage 🙂 . I’m going to assume user is comfortable with Ubuntu.This should work with Ubuntu 11.x too.

  • Create Apt source

Create /etc/apt/sources.list.d/mongodb.list
Add the following line to the above created file : deb http://downloads-distro.mongodb.org/repo/ubuntu-upstart dist 10gen

  • Add the GPG Key and Update Index

sudo mkdir /etc/apt/trusted.gpg.d/

sudo apt-key adv –keyserver keys.gnupg.net –recv 7F0CEB10

sudo gpg –export richard@10gen.com | sudo tee /etc/apt/trusted.gpg.d/mongodb.org-keyring.gpg > /dev/null

sudo apt-get update

sudo apt-get upgrade

  • Install MongoDB

sudo apt-get install mongodb-10gen

Have fun!

The Rise of NoSQL data stores


NoSQL is a movement promoting a loosely defined class of non-relational data stores that break with a long history of relational databases. These data stores may not require fixed table schemas, usually avoid join operations and typically scale horizontally.
Basically the data won’t be stored as table/matrix as most of us have come to know how a basic DB looks like.Relational data is easy to understand for most applications but scalability & performance take a hit or its a trade off between convention over being faster & large.
Data processing performance & scalability,as most CS graduates would agree, is hugely influenced by underlying data structures like map,trees,graphs etc.The NoSQL movement is gaining traction due to the toll man’s principle “Using the right tools for the right job”
