ROR is an open-source framework introduced by David Heinemeier Hanss that operates on the prominent concept of MVC (model-view-controller). This server-side web application framework is written using Ruby under the license based on MIT.
The ROR, also fondly known as Rails operates on several web servers and supports DB2, Oracle, SQL Server, SQLite, PostgreSQL, and MySQL.
Furthermore, ROR emphasizes making efficient use of software engineering paradigms and patterns. Some of them include Convention over Configuration (CoC), active record pattern, and don't repeat yourself (DRY). ROR framework has brought a revolutionary phase in the web app development process with its innovative tools.
The ease of database table creation, migration, and scaffolding of views allow faster software development. This popular PHP framework
creates room for speedy and easy development.
David Geary, a Java expert has clearly defined the ROR framework 5 to 10 times faster than any other Java-based framework. Inarguably, ROR has set a benchmark which the several other frameworks are still trying to win over.
