7. Model-View-Controller (MVC)
• The Model represents your data structures. Typically your model classes will
contain functions that help you retrieve, insert, and update information in
your database.
• The View is the information that is being presented to a user. A View will
normally be a web page, but in CodeIgniter, a view can also be a page
fragment like a header or footer. It can also be an RSS page, or any other
type of “page”.
• The Controller serves as an intermediary between the Model, the View, and
any other resources needed to process the HTTP request and generate a
web page.
