If you are experienced in using DBI, you could take a look at DBD::AnyData. As long as your data is being stored in an AnyData compatable format, you should be able to use a simple SQL command to retrieve your info:

  my $dbh = DBI->connect('dbi:AnyData(RaiseError=>1):');
  $dbh->func( 'STUDENTS', 'CSV', 'students.csv' );
  my $sth = $dbh->prepare("SELECT degree FROM STUDENTS WHERE STUDENT =
+ 'george'");
