Ruby On Rails Learning and Training Content

Ruby on Rails is an open-source web application framework designed to make the job of the developer easier by providing everything one needs to create web-based, database-driven applications easily while focusing on the idea, not the technology behind implementing the idea. It is designed to be a marriage of the “quick-n-dirty” camp of PHP web developers and the “slow-n-clean” methodologies of the old enterprise architecture crowd. Ruby on Rails succeeds by automating the creation of the most common types of Web applications while not straightjacketing you if you want to add custom or atypical requirements. Moreover, compared to many Free Software libraries that perform individual aspects of a Web application, Rails contains a nicely integrated set of tools for all aspects.

Ruby on Rails is taking Web development by storm. Let's start with a refresher on the underlying technologies:

Ruby is the free, simple, straightforward, extensible, portable, interpreted scripting language for quick-and-easy object-oriented programming that, like Perl, sports many features to process text files and perform system-management tasks.
Rails is a full-stack, open source Web framework in Ruby for writing real-world applications with more ease and less code.

Being a full-stack framework means that all layers in Rails are built to work together so you don't repeat yourself and can use a single language from top to bottom. Within Rails, everything (templates to control flow to business logic) is written in Ruby. Rails favors reflection and runtime extensions over configuration files and annotations.

Software Architecture Case Study: Ruby on Rails (24 pages, 385kb, pdf format)
A high-level view of the Rails architecture makes it look very much like other web application frameworks. Its architecture is based on MVC, designed to separate concerns and reduce the coupling between disparate functionality. Part of Rails’ power comes from the fact that this architecture is connected through an auto-generated code base structure. The developer can set up a project and then make changes to the model directly and observe the results without a lot of work to set up every part of getting that data propagated throughout the rest of the system.

The entire benefit of using Ruby on Rails is in many of the small things it does to benefit the developer in ways that other similar frameworks do not. These little things collectively work together to create a development experience which overall seems much more agile and less cumbersome than the process involved in working with other large and robust web development architectures.
