Ruby on rails or simply Rails is basically a server side web application framework written
in Ruby under the MIT license. Default structures for a data base, a web
service and web pages etc are provided by the framework of model view
controller is a rail. The web structures such as JSON or XML and their use is
encouraged and facilitated by it. Apart from these the use of other well known
software engineering patterns and paradigm are emphasized by the Rails. The
convention over configuration (Coc), don’t repeat yourself (DRY) and the active
record pattern. Ruby Gems a package manager is being used by installation of Ruby on Rails

being not connected directed to the internet. It is also supported natively on
the IBM. In the early days some front end web server Mongrel was generally

A default configuration a model in it framework maps to a
table in a database and to a Ruby file. For example a model class User will
usually be defined in the file’ user’ in the app/models directory and linked
to the table ‘users’ in the database. In accordance with the “convention over
configuration” philosophy it is generally discouraged and seems to be not
common practice like choosing differing names for their models, files and
database table and developers are free to ignore. A view in the default
configuration of Rails is an erb file which is evaluated and converted to HTML
at run-time. Alternatively, many other templating systems can be used for views.
