use the create(String data) to create a new record,
every field have itself length(32,64,6,8,8) in the record ,
but the user data's length be likely to less than the field's length(32,64,6,8,8),
the name field's length is 32 in the db file ,
the new record's name filed's length is 5(example:"Jofer"),
how does the new record's name write into the db file?
Does append the 27 blanks to the "Jofer" with the "for" statement?
