How does the new Content Server 7.5 connect to the MaxDB database ?

Dear Experts,

Although there is quite some documentation about the new Content Server 7.5, I still have the impression, that
a lot of important stuff is not really explained.
I keep asking myself - how does the Content Server application know how to connect to the MaxDB database.

When installing both products (which now happens through 2 separate executions of SWPM), there is no screen,
where one could configure a connection to the database.

And I also keep asking myself - isn't it necessary to create a DB connection to the MaxDB database from SAP ?

Many thanks for any clear and brief replies :-)
