What is Ruby on Rails?

Ruby on Rails is a framework for developing web-based software. It is implemented in the Ruby programming language, a back-end language. 

Ruby by itself was created in 1993 by Yukihiro Matsumoto and is a flexible and precise language. It allows for the possibility of organizing written code in a more efficient way. The Ruby syntax is based on blocks of code, so errors are avoided when changing the instruction line.

The Ruby language, however, did not rise to international fame until 15 years later, in 2008, five years after being combined with a framework called Rails. 

Rails extends the Ruby language in the same way that .NET, Spring, or Django extend C#, Java, or Python, respectively.

This combination resulted in the framework known now as Ruby on Rails (RoR). ROR has seen an increase in popularity among developers in recent years because of its simplicity and its foundation in agile methodologies.

Why Ruby on Rails?

Rails offer the full range of functions for the development and operation of a web application such as:

  • Connection to all relevant database systems
  • Implementation of controllers
  • Answer inquiries from the WWW
  • Its own template functionality for preparing the data 
  • Own routing engine for configuring the query and response behavior.
