*Ruby on Rails development=http://www.railscarma.com/ is basically a web application
development framework which is normally written in Ruby. Rails MVC
framework, provides default structures for databases, web services and
web pages. It uses typical web standards like JSON or XML for data
Ruby On Rails Technical overview
Like many of the web application development frameworks, Ruby on
Rails generally uses the model view controller yupp it's MVC to
organize application programming.
In it's default configuration, a model in the Ruby on Rails MVC framework maps a table in a database to a Ruby file.
Ruby on Rails Development includes serveral tools that make most of
the web application or normal application development tasks easier ,
such as scaffolding that automatically build models and views which is
needed for a basic website. Next is WEBrick is a Ruby library provides
simple HTTP web server services. Both of these tools provide a basic
ruby on rails development environment.
Ruby On Rails Framework structure
Ruby on Rails is divided into several various packages like
ActiveRecord ( for database access using objects relational mapping),
Active Resource (that generally provides all web services), Action Pack,
Active Support and Action Mailer.
Ruby On Rails Deployment
Ruby on Rails is usually installed using RubyGems( a package manager
which contains current versions of Ruby). Many free Unix systems also
support Ruby on rails installation and its dependencies via native
package management system.
Ruby on Rails is basically deployed with a database server such as MySQL or PostgreSQL and a web server such as Apache.
Ruby on Rails is basically emphasize on Convention over
Configuration (CoC) where developer only needs to specify just
unconventional aspects of the application and that's it. and the Don't
Repeat Yourself (DRY) principle it means there's one unambigiuous place
where all the the imformation is present or located.
"Convention over Configuration" means a developer only needs to
specify unconventional aspects of the application. For example, if there
is a class Sale in the model, the corresponding table in the database
is called sales by default. It is only if one deviates from this
convention, such as calling the table "products sold", that the
developer needs to write code regarding these names. Generally, Ruby on
Rails conventions lead to less code and less repetition.
"Don't repeat yourself" means that information is located in a
single, unambiguous place. For example, using the ActiveRecord module of
Rails, the developer does not need to specify database column names in
class definitions. Instead, Ruby on Rails can retrieve this information
from the database based on the class name.
