Basically there is only a design pattern with 3-tier architecture. 4-tier OR N-tier depends upon one's own module and software handling. 3-tier architecutre basically means u have following tiers 1) Presentation Layer 2) Business or Logic Layer and 3) Data Layer

The idea behind this is to develop and maintaint the three tiers independently without affecting each other. For ex take a look at MVC architecuter, it is a classic example of 3-tier. You can either use JSP or any other presentation layer without changing the controller and model layer.

4-tier or N-tier is basically enhanced versions over 3-tier...the more u modularise your architecture the more tiers one will have.
