SQLServer has real databases with its own transaction log files.  You can restore individual databases in a cluster.
They also have schemas which are not same as users (Oracle treats users and schemas same).

For security, there is grant connect to the DB and further filtering based on schema.

I find SQLServer implementation pretty strong in this.  

The only time this can be a problem is when few databases failover in a mirrored environment (streaming replication in
PGspeak).
 
Then suddenly 3 part names would fail if the remote DB is no longer primary. My experience with SQLServer is badly
dated.Last 
 
time I worked was SS2008.  I believe in later versions they solved this problem by the failover group concept which
failoversall
 
inter-related databases at one go.

BTW Mysql treats databases and schemas as same (that's what it was few years ago)
