One of the problems with this architecture is that there can be a tendency for business-logic and data-access code to migrate up through the tiers until it is irrevocably intertwined with the user interface code. With ASP.NET Web Forms, which support the n-tier architecture, you do need a degree of discipline to ensure that this does not happen. It is all too common to see ASP.NET applications where SQL queries are hardcoded as strings and embedded into data access code within an event handler of a web control.
