Ruby on Rails (RoR), also known as Rails, is a robust web development environment tailored for creating web applications using the Ruby programming language. It employs the Model-View-Controller (MVC) architecture, dividing the application into the model, view, and controller components. This structure enables developers to write concise yet highly functional code, streamlining the development process efficiently.

RoR supports various database management systems such as MySQL, PostgreSQL, SQLite, IBM DB2, Oracle, and Microsoft SQL Server, enhancing its adaptability in web application development. This versatility allows developers to select the most suitable database system for their project needs, catering to both large-scale commercial data and smaller, agile databases. The capability to integrate with multiple databases makes RoR a flexible tool for diverse development requirements.
