ORS is a state agency with limited web development resources, so it uses several open source tools like Ruby on Rails, mySQL, Nginx, and Thin to build its applications rapidly and reuse code. Ruby on Rails provides a model-view-controller architecture and ActiveRecord object-relational mapper that allow for quick prototyping and development. Ruby is also a powerful language that can express business logic concisely. Using these open source solutions has given ORS flexibility in its technology choices.
