4D v14
Switching to client/server mode
Switching to client/server mode
In addition to the manipulations explained in the video, you should also note that:
Use in client/server mode is very simple.
Triggers are executed on the server.
You must not use commands that interact with the user (ALERT, DIALOG, CONFIRM, Request, etc.) since no one is in front of the server to validate them, especially when the server is running as a service.
We can execute processes (stored procedures) on the server.
