Since you were quoting me, I will bite.

In the context it was written, business logic is the rules that govern how the data items are processed, display logic is how the user sees them. In the broad sense, yes, display logic is a part of business logic. But so is where you park and what entrance the employees are allowed to use.

In the context written, the distinction is made because it separates concerns. If Joe needs to fiddle a frobnotz and have the results displayed as a table, but Jane needs to fiddle the same frobnotz and have it displayed as a graph, why should the anything but the display side of things care. The frobnotz needs to be fiddled the same way. I would have my CGI connecting script (mod_perl handler, etc) fiddle the frobnotz and hand the results off to the right display module.

I better get back to work now, before my $workplace blocks access due to use of euphemisms.
