ERP application - what would be the best approach?

[eluser]Unknown[/eluser]
Hello,

I am looking to create a ERP application using the MVC model proposed by CI. My first idea is to use a HEADER/MAIN/FOOTER type of application, using controllers for the header and footer, so it is easy to change the format of the page if I want to display/print in different media.

I would like to know your opinion on that and if you could provide me with an example in this matter.

Thank you and all the best,

Rom
