MVC will divide an application into three functional parts: Models  — deals with your database, carries out computations, and more. In short, it is where your business logic is located. Views  — forms the presentation layer of the application, where the data from your  models  are embedded. Controllers  — used to connect  models  and  views . A controller will route user requests to the appropriate  model.  After that, once the model has done its job, the controller loads the relevant  view. This architectural pattern also gives developers the flexibility to reuse code for multiple views. For example, you can apply the same navigation bar on every webpage of your application. Moreover, as both  views  and  models  are entirely separate, the front-end developers can work in parallel with the back-end team to speed up the development process. Note that CodeIgniter also subscribes to  Object-Oriented Programmin...
