It doesn't
Access is a desktop, principally designed for power users and single user desktops systems. All attempts to use is as a DBMS are doomed to at best, a limited failure.
You will hear otherwise, but as a client server DBMS it just sucks, so if you want one, or you expect to scale to one at some point in the future, don't go near it. There used to be an excuse in that it came 'free' with MS Office, given MS's free limited products and other offerings on the market, that's no longer valid as a reason to use beyond it's capacity.
