I have seen some databases product that allocate small number of large files.
Please correct me if I am wrong:
MSSQL (one file is the data and another file for the transaction log)
MySQL with InnoDB

I don't know enough about DB2 and MSSQL, but you are correct
with regard to InnoDB and Oracle.

MSSQL can use several data files, but in general, you will have one for
database data, and one for database log.
Advanced administrator would choose to split database among several
files (specially in sparse disks). For instance, you would have one data
file in one SCSI disk for data, and one data file in another SCSI disk
for indexes, and a third SCSI disk for log. You can have several
(hundreds? thousands? I can't remember) data files.
