Connecting one data base to another

I was wondering if there is a way to send data from a gaming server or a website and sending that to a and using that data from the gaming server or the website to display it on a app? I also wounder if there is a way to use a app to send data to a gaming sever or website as well. If anyone could help me with this question and walk me through how to do it I would greatly appreciate it!

Maybe check out the SQL connector in the plugin marketplace? It is free.

Thank you
