Could someone please post a perl skeleton for fast insert/lookup for a really simple but persistent data base? Something like:

my $numofwords= 50000000;
my %randomword;
for (my $i=0; $i<$numofwords; ++$i) {
  my @chars = ( "A" .. "Z", "a" .. "z", 0 .. 9, qw(! @ $ % ^ & *) );
  my $rin = join("", @chars[ map { rand @chars } ( 1 .. 5 ) ]) ) };
  if (defined($randomword{$rin})) { $randomword{$rin}.=",$i"; } else {
+ $randomword{$rin} = $i; }
}

so, my data base can be very large (50 million words), but its structure is very simple. A key can have multiple records, but they are not complex. insertion and lookup speed are important.

I have tried a version with DBI and SQLite, but insertion was very, very slow. then again, this is the first time I am using a data base, so my attempts were rather naive.

advice appreciated. /iaw

• Are you posting in the right place? Check out Where do I post X? to know for sure.
• Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>

• Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
