2.1. Not a Mockup

A few years ago, I demonstrated an application that did what I just described. The demo ran for more than 2 hours with the same questions repeated over and over.

"It's a mockup, right?"

"No, it is the actual application."

"It can't be. The screen doesn't blink."

"That's because XML, HTTP, and SOAP are used to get the data directly from the server. JavaScript then updates only the parts of the page that have changed."

"It's a mockup, right?"

And so on. It took the client more than 2 hours to realize that the database was actually being updated without the page "blinking," as he referred to it.
