Ruby on Rails — A web-app framework that includes everything needed to create database-backed web applications according to the Model-View-Controller (MVC) pattern.
A web-app framework that includes everything needed to create database-backed web applications according to the Model-View-Controller (MVC) pattern.
Ruby on Rails, often simply Rails, is an open-source web application framework written in Ruby. It is a server-side web application framework that provides default structures for a database, a web service, and web pages. It encourages and facilitates the use of web standards such as JSON or XML for data transfer, and HTML, CSS and JavaScript for display and user interfacing. In addition to MVC, Rails emphasizes the use of other well-known software engineering patterns and paradigms, including convention over configuration (CoC), don't repeat yourself (DRY), and the active record pattern.

Key Features of the Site
Convention over Configuration
Rails has opinions about the best way to do many things in a web application, and defaults to this set of conventions, rather than require that you specify every minutiae through endless configuration files.
Don't Repeat Yourself (DRY)
DRY is a principle of software development which states that 'Every piece of knowledge must have a single, unambiguous, authoritative representation within a system.' Rails helps you adhere to this principle by ensuring that your code is as concise and maintainable as possible.
Active Record
Active Record is the M in MVC - the model - which is the layer of the system responsible for representing business data and logic. Active Record facilitates the creation and use of business objects whose data requires persistent storage to a database.
Scaffolding
Rails scaffolding is a quick way to generate some of the major pieces of an application. If you want to create the models, views, and controllers for a new resource in a single operation, scaffolding is the tool for the job.
Migrations
Migrations are a convenient way to alter your database schema over time in a consistent and easy way. They use a Ruby DSL so that you don't have to write SQL by hand, allowing your schema and changes to be database independent.
