Comparison of 2 3 and 4 Tier Models
Two ways of Implementing Data Objects
Today’s Pragmatic Object Web: The Confusing Multi-Technology Real World Middleware Server Layer
Todays Complex World will evolve to something like the pure CORBA Architecture for a distributed Information System (There are similar COM and Javabean /RMI Versions)
