Lightweight models & cost-effectively scalability: Ruby On Rails


Ruby is a dynamic, reflective, general-purpose object-oriented programming language that combines syntax inspired by Perl with Smalltalk-like features. Yukihiro “Matz” Matsumoto created Ruby, an object-oriented language Matsumoto hoped would focus on the needs of humans to the programmers instead of the needs of machines.

Ruby has been regarded as a Language that allows “Rapid Development and Prototypes”, which is important for developers as the lesser time we spent bashing the keyboard, the more time we have to design and work on those cool features.

The mature language is supported by a number of easy-to-use tools, including Gems, which lets Ruby developers speedily, update their Ruby installations and integrate add-ons with simple text-based commands. And then there’s Rails.

‘Rails’ is a Ruby-based Web development framework that tailor-built for productivity. The emphasis of ‘Rails’ is on convention. A Rails app is largely preconfigured to as long as you stick to the required directory structure and file-naming conventions and it handles a lot of the behind-the-scenes tedium for you.

For instance, building a web-fronted database app in Rails takes about ten minutes. ‘Rails’ automatically generates the interfaces necessary for adding, editing, viewing and deleting database entries. Even though the default interfaces are not appealing but you can quickly customize things to suit your exact needs. In about an hour, you can put together a basic database-driven app for a project you are tracking. The advantage with Rails is that you don’t have to suck a lot of time from other parts of your time to get things rolling. You will be just hanging your ideas off the pre-built framework.

Rails as it can generate basic base codes for developers looking to create web application, which developers benefit from the “Structured Code and Neat Markup” for developing their web application based on MVC architecture. In addition, “Interchangeable Databases” and “Database Schema Control” will save developers by allowing them to start developing their application using sqlite, which is the default database available right after creating the Rails web application, so developers could work on features that require database without having to setup database.

There are dozens of commercial sites that involve Rails and Ruby and Rails book sales are apparently going through the roof.
