@db contains hash references.

     @db1 = sort { $a->{category} cmp $b->{category} } @db;

or, by sorting the indices:

     @db2 = @db[ sort { $db[$a]{name} cmp $db[$b]{name} } 0 .. $#db ];


Since both resulting arrays store the same hash references, the records
themselves are kept in memory only once.
