What is Ruby?
Ruby is a pure object-oriented programming language with a super-clean syntax that makes programming elegant and fun. Ruby successfully combines Smalltalk's conceptual elegance, Python's ease of use and learning, and Perl's pragmatism.
What is Rails?
Rails is an open source Ruby framework for developing web-based, database-driven applications. There are dozens of frameworks out there, and most of them have been around much longer than Rails.
