Description: Ruby on Rails is a server-side web application framework for creating database-backed web applications. This technology is a Model-View-Controller (MVC) framework, providing default structures for a database, a web service, and web pages. The Model layer represents the domain model (such as Account, Product, Person, Post) and encapsulates the business logic that is specific to the application. The ActiveRecord module allows the developer to present the data from database rows as objects and embellish these data objects with business logic methods. Although most Rails models are backed by a database, models can also be ordinary Ruby classes, or Ruby classes that implement a set of interfaces as provided by the ActiveModel module. The View layer is composed of templates that are responsible for providing appropriate representations of the application`s resources. Templates come in a variety of formats, but most view templates are Hypertext Markup Language (HTML) with Embedded Ruby (ERB) code. The Controller layer is responsible for handling incoming Hypertext Transfer Protocol (HTTP) requests and providing a suitable response. Usually this means returning HTML, but this technology`s controllers can also generate other formats, including Extensible Markup Language (XML), JavaScript Object Notation (JSON), and Portable Document Format (PDF). Controllers manipulate models and render view templates in order to generate the appropriate HTTP response.

This technology is typically deployed with a database server and a web server. By default, this technology utilizes Structured Query Language Lite (SQLite), however, any relational database management system (RDBMS) can be used. Also, this technology includes a built-in web server, however, any web server can be used.

Users must ensure sensitive data is properly protected in compliance with all VA regulations. Prior to use of this technology, users should check with their supervisor, Information Security Officer (ISO), Facility Chief Information Officer (CIO), or local Office of Information and Technology (OI&T) representative to ensure that all actions are consistent with current VA policies and procedures prior to implementation.
