In the case of a DB journal, back in the mainframe days, we used to run 
the journal life to a tape. 

Database systems can be complex because there may be multiple steps 
before a transaction is commited. 

For a database in a dedicated filesystem, it is probably best to use a 
non-journalling filesystem and use the DB journal. That way you will 
probably get better performance.  Each database is different has has 
different journalling capabilities and strategies.
