No, go back and read.
The 'back end' was a SQLServer db with stored procs. The code itself was only 2-tiered, not 3-tiered as I would have done. They put the 'business logic' in the SPs, in the DB. I would have seperated that logic out into the middle-tier, personally, but that wasn't the project he described.
Seriously, he gave plenty of detail, and any decent developer could have built it. A web form that sent procs to an SP, and then wrote links to the screen.
Very simple stuff. Not rocket science at all.
