For a 3 tier system to work the code required will have to be different from the code needed to make a 2 tier system work. The reason behind this is, in a 3 tier system, the web server will have to make requests to code that resides on a physically different machine, i.e., the application server.

    Benefits of a 2-Tiered system. A 2-Tiered system basically eliminates the web server and the application speaks directly to the database. Performance: Because of tight coupling, a 2 tiered application will run faster. The absence of a network hop ...
