"storage engine". Even though normally accessed by a DBMS with the underlying functioning procedure (and sometimes using the operating systems' file devices as intermediates for storage format), storage properties and configuration options are very important for that effective Procedure with the DBMS, and therefore are carefully taken care of by database directors.
