Would you set up a new database? Because our database (being a forum) isn‘t the best for giving everyone access...
If there is no online database already that German staff members use, then I would make one. It's basically an excel spreadsheet on Google Drive, and it's easier for both the NT manager and staff members, if everyone can work on the same file.
The ownership of the file can change, so once I make it, I would pass the ownership to one of the staff members, perhaps to a manager who is serious about running in the next term.
I can make arguments for why it can be beneficial if more users could see the database, but in the end, it shouldn't be up me to decide something like that for your community. And there's no need to rush such a decision. There's more arguments to be made on that topic, and it should be left after the elections are over.
The ownership of the file is passed on to every new NT manager in the future, so they would be in charge of the database. And once my term ends, next NT manager would remove me from the group of people who can access it.
