help for DELPHI4 client-server application

I have recently got the DELPHI4 client server suit and I have some
trouble to set a simple client server application using any  database.
Could any one help me to write a server  and a client  with the tricky
components like Corba connection, Tprovider, Remote server, ...?
First, I wonder what are the right components to get  connection between
my client and the distant server ...
I would be very happy to get a working example!

julien who hope to hear about you
