Why mongodb? My views on mongodb

Why mongodb? My views on mongodb. Please share your views as comments.

1. Mongodb is open source database written in C++. It has drivers for most of programing

language Python, Ruby ( I am going to use ), Java etc.

2. Mongodb is not relational database like mysql, it is document oriented database

(NOSQL).

3. Data Storage: Relational database saves datas (columns) record in table (rows). But in

mongodb, it is document oriented, data are stored as JSON format (BJSON – Binary json).

Documents are like database and collection are like tables. Data can be accessed as

key-value. So it is very fast and reliable.

4. It does not have joins like RDBMS, it uses linking and embedding technique. So it does even

complex query faster.

Experience in conducting workshop

Mr. Thyagarajan Shanmugam, CEO of open vidhya (my mentor) conducted workshop in Coimbatore institute of technology on September 1st and 2nd 2012. He took class on PHP and Ruby. Some basic on Ruby on rails. Students in CIT were eager in learning new technology. Me also helped some students by clearing some doubts.

English to tamil offline dictionary

Code was written in ruby,

Database: sqlite3

Download Files here

File: word.rb

Connecting database using sqlite3 adbapter and active_record ORM.

File: install.sh [only for debian package]

run install.sh

$sh install.sh

Others should install

ruby, rubygems

gems: sqlite3, active_record, nokogiri

File: upload.rb

You dont need to run this script. if you have word.db file. This ruby program scraps

all word and meaning from http://ta.wiktionary.org/wiki/%E0%AE%AE%E0%AF%81%E0%AE%A4%E0%AE%B1%E0%AF%8D_%E0%AE%AA%E0%AE%95%E0%AF%8D%E0%AE%95%E0%AE%AE%E0%AF%8D

and save into sqlite database.

File: word.db

This is database of all words and meanings  which was saved by upload.rb script.

This application has autocomplete functionality.

This is first version of script. code was in repo, url: https://github.com/sathia27/dictionary

Feel free to edit the code. You can change to any languange instead of tamil by making some changes to upload.rb.

How to run

After installation,

Go to that folder and run dict.rb

$cd dictionary
$ruby dict.rb
