What is the best way to write a client-server application in delphi? I know that there is DataSnap technology, but this is not in the professional version. Do you have any experience you can share?
This is a fairly open-ended question, as it may depend on your decision in the database.
DataSnap really allows you to use N-Tier solutions, if you are looking for Client Server you have most of everything that you need in the professional version, depending on the choice of database.
For client server:
The architecture of the client server is when the client communicates directly with the server.
Several frameworks are available, they all follow the same template.

App Server
You can use our lightweight MsgConnect product to exchange data between the client and the general-purpose server . This is a cross-platform MOM (message-oriented middleware).
