What do ARIS Connect database privileges mean?

Hi

In ARIS Connect, on a versionable database, there are nine possible values (see attachment) for a user's database privileges. Please can someone explain a) what they do, b) how they differ from each other, and c) is there a way of seeing a user's existing privileges before opening the drop-down list?

I've checked the ARIS Adminstration Help but it just says 'select the one you want'; it gives zero guidance about what they mean. I've searched the Community but after trawling several pages of posts could not find an answer.

Thanks, Simon
