There are a number of definitions of a database machine, though the one most
commonly used is a computer (usually a mini) set-up as a slave to a host
computer which is dedicated to database processing. The database machine
usually runs a standard DBMS.                  

The database machine offloads much of the database processing from the
host computer. Since database processing is often CPU bound (lot of work is
required to translate a users logical requests for data into physical 
storage locations), having a database machine can speed operations, since
the host computer can be doing other things besides address translations.
People seem to feel that a database machine increases throughput.

Does that help?
