Thank you, really appreciate the feedback. The MVC (model-view-controller) framework requires more in depth description and code examples, which I am fully aware of. In near future, I’ll go more in depth on MVC structure.
However, the main takeaway of MVC is that it separates code to simplify the programmers work. You have one part that handles user interaction (view), another part that speaks to the database (model) and a third part that handles the logic (controller).
Here is a link about MVC that may be beneficial for you, includes code examples too.
