Centrally controlled preferences

Hello everyone,
I would like to install a central control of settings for my university. The goal is to have preset settings both through the app and through the dashboard. I also have a PDF file with instruction steps so that the settings are controlled through a database. However, I am not that familiar with it, especially the environment editor. I am not even sure, if the databade mode is the best solution. Is there a suitable person who can help me?
I have attached the PDF document.

Best Regards
