Web Application Process in ruby on rails - MVC web server access :

Step 1 : A user clicks a link to a page in a web application

Step 2: The web server recieves the request URL (Universal Resource Location - Uniform Resource Locator). Rails uses a routes file to match the URL with a controller action.

Step 3: The invoked controller action requests data from a model. The model queries the database and hands data back to the controller

Step 4: The controller action then passes data to a corresponding view. The view uses the data and a template to compose a page.

Step 5: The controller passes the complete page to the web server.

Step 6: The web server serves the page to the browser. The browser renders the new page in place of the first one.

Step 7: Ruby on Rails provides a framework for this MVC flow. It enables developers to work on what makes their apps unique rather than spend time re-implementing conventions.
