楼上的好像说的不太对吧~~
先来段英文的,2层和4层存放结构:
==
In the two-tier deployment, the Java based rich client, the enterprise-tier server and the supporting software run on the users’ workstations. Database, volumes and other resource-tier components run on separate systems.
In the four-tier deployment, only the Java based rich client runs on the users’ workstations. The enterprise tier, database, volumes and other resource-tier components run on separate systems.

普通的用2-tier 就可以了。
Web端是用来远程的。
四层架设比较麻烦,但是有些功能只能4-tier上用。
