Oracle data is stored in a set of one or more pieces of pre-allocated
disk storage, where each piece may be a Unix file or a raw partition.  
The Data Base Administrator may add additional pieces, as needed.  Note
that tables may span files/partitions.

Once a raw device has been added to a database, there is no difference in
administration.
