We describe the implications of a modern multi-tier Enterprise system where a server does not just get web pages but is a general host of services which are linked together to solve complex problems |
These servers can respect any of the 4 distributed object models CORBA, Java/RMI, COM or W3C's XLM WOM/DOM |
We illustrate these ideas with an analysis of a multi-protocol server JWORB -- written in Java but serving all protocols |
We point out how a multi-tier architecture allows you to build backend systems to increase performance when necessary |
