Ruby on Rails

Information Technology > Programming frameworks

Description

Ruby on Rails, often just called Rails, is a popular web application framework written in the Ruby programming language. It follows the Model-View-Controller (MVC) architectural pattern, promoting the use of web standards and simplifying the coding process. Rails provides tools to handle routine tasks, such as URL routing, database interactions, and HTML generation, allowing developers to focus on business logic. It also encourages best practices like RESTful application design and convention over configuration. Learning Rails involves mastering Ruby syntax, understanding MVC and REST principles, using Rails-specific features like generators and migrations, and eventually, optimizing performance and contributing to the Rails community.
