Ruby on Rails uses the Model-View-Controller (MVC) architecture pattern to organize application programming. Ruby Supports multiple programming paradigms, including functional, object-oriented, imperative and reflective. It is a metaprogramming language which has a dynamic type system and automatic memory management. Rail is an open source Ruby framework for developing database-backed web applications.
The MVC design pattern separates the component parts of an application.MVC pattern allows rapid change and evolution of the user interface and controller separate from the data model. Rails can run on most web servers that support CGI.the framework also supports MySQL, PostgreSql, SQLite and Oracle.
There are two major guiding principles in ROR:
Don't Repeat Yourself
DRY is a principle of software development which states that every piece of knowledge must have an authoritative, unambiguous, single representation within a system. If same piece of code will not repeat again and again, code will be more maintainable, extensible and less buggy.
Convention over configuration
Rails doesn't need much configuration. The total configuration code can be reduced by common conventions. Naming your data model class with the same name as the corresponding database table and id as a primary key name.
Scaffolding create temporary code in the early stages of development to help get an application up quickly and see how major components work together.
Active Record framework
It saves the object to the database. Discovers the columns in a database schema and automatically attaches them to domain objects using metaprogramming.
Action pack breaks a web request into view components and controller components. An action usually involves a controller request to create, read, update, or delete (CRUD) some part of the model, followed by a view request to render a page.
Advantages of using RoR are
High code quality
Ruby On Rails is getting popular in big corporations, giant enterprises to develop robust, effective and mission critical web applications. More and more companies are now focusing Ruby on Rails development to deliver extensive web products and website developed on RoR platform. So it is difficult to find the best one.Here we have given the top companies that match your requirements.
