Ruby on Rails - UNISO
Ruby on Rails is a web application framework written in Ruby. It is designed to make programming web applications easier by making assumptions about what every developer needs to get started. It emphasizes using less code by convention over configuration. Some key aspects include using the MVC pattern, active record for database access, and test-driven development. The Rails community is large with over 45,000 libraries available to help developers.
