3-tier client-server

I have a simple query. A 3-tier architecture is very obvious in an Oracle web environment i.e. RDBMS Server, Application Server and the client.

However, can someone please explain what a 3-tier architecture means in a client-server environment. I don't want the theory here, I understand the principle of seperating intensive process-logic from the Userinterface.  But, let's say I'm using Oracle Developer and Oracle 8.05 in a client-server environment. - What configuration/components would transform the standard "2-tier" configuration into 3 or more tiers.

Thanks in advance.
