Introduction to Ruby on Rails
Ruby on Rails is an open-source
web framework that is optimized
for programmer happiness and
sustainable productivity. It lets
you write beautiful code by
favoring convention over
configuration.
People10 Technosoft Private Limited | 2013.01
Ruby on Rails is a breakthrough in
lowering the barriers of entry to
programming. Powerful web
applications that formerly might
have taken weeks or months to
develop can be produced in a matter
of days.
-Tim O'Reilly, Founder of O'Reilly Media

Why so?

6. 6
Simpler Approach
People10 Technosoft Private Limited | 2013.01
Ruby on Rails solves the
common architectural
problems that existed in
traditional application
development, like:
» Persistence
» Logging
» Build scripts
» Application
configuration
» Web tier components
» Workflow

7. 7
Convention over configuration
People10 Technosoft Private Limited | 2013.01
» Ruby on Rails favors
convention over
configuration
» A developer only needs to
specify unconventional aspects
of the application
» No need for one large
configuration file
» Less time will be spent on
defining obvious things which in
turn will increase productivity

8. 8
Do not Repeat Yourself (DRY)
People10 Technosoft Private Limited | 2013.01
» DRY is a design principle
which is used in Ruby on
Rails to reduce the repetition
of information of all kinds
» DRY code is created by data
transformation and code
generators
» DRY code usually makes
large applications easier to
maintain

9. 9
Active Record Pattern
People10 Technosoft Private Limited | 2013.01
» Active Records provides an
interface and binding
between the tables in a
relational database and the
Ruby program code that
manipulates database
records
» Allows simple designs and
straightforward mappings
between database tables and
application objects.

10. 10
Model View Controller
People10 Technosoft Private Limited | 2013.01
» Ruby on Rails follows the
Model View Controller
(MVC) architecture
» Helps in addressing the
issues of code reusability and
separation of concerns
» With the help of Ajax,
Backbone etc. MVC can be
executed partly on the client

11. 11
Dynamic nature
People10 Technosoft Private Limited | 2013.01
» Ruby on Rails simplifies
the client code behavior
» Generation of dynamic
content – web pages,
emails, xml documents
etc. is easy
» Can inject independent
code into classes, blocks
and closures

12. 12
Database Persistence
People10 Technosoft Private Limited | 2013.01
» The model of Ruby on
Rails is seamlessly
persisted to the
database
» Implementation of
database migrations for
applying and rolling back
database changes is
seamless

13. 13
Behavior Driven Development
People10 Technosoft Private Limited | 2013.01
» RSpec, a Behavior
Driven Framework for
Ruby
» Testing is more about
writing specifications of
the behavior of the
program
» Software components can
easily be tested without
resorting to external tools
or generators

14. 14
Supports Agile
People10 Technosoft Private Limited | 2013.01
» Jenkins CI, for continuous
integration
» Cucumber for test driven
development
» Capistrano for deploys
» Collaboration tools like
Jira, and Pivotal tracker
» Supports Total agile
development

15. 15
Cloud Ready
People10 Technosoft Private Limited | 2013.01
» Ruby has already been
named as the “Language
of the Cloud”
» Companies like Heroku,
Engine Yard and
Morphlabs are utilizing
Ruby at its fullest to glue
their cloud platform
