Ruby on Rails Overview

1. Project Design Using Ruby on Rails
1) The browser will send request to the
controller.
2) The Controller will fetch data from the model
layer.
3) The Model layer will fetch data from the
RDBMS
4) Based on the business data logic an ORM
will be created by the model layer.
5) The Controller will receive data as objects
and do some processing.
6) The Controller will send a response back to
the view layer.
7) The view layer will present that data to the
browser and render the data by using HTML
CSS and javascript.

4. SASS
• Fully CSS3-compatible
• Language extensions such as variables, nesting, and mixins.
• Many useful functions for manipulating colors and other values.
• Advanced features like control directives for libraries.
• Well-formatted, customizable output.
• Firebug integration.

5. JQuery
• Less lines of code to achieve the same feature in comparison.
• JQuery enables you to perform many functions in comparison to
other Javascript libraries.
• Ajax support
JQuery lets you develop Ajax templates with ease, Ajax enables a
sleeker interface where actions can be performed on pages without
requiring the entire page to be reloaded.
