Also, I just realized I was thinking DB_File hashes, which I use from time to time. Did you mean something else?

UPDATE: nearly the same thing. In fact, for all we know, dbmopen may just use DB_File... see: AnyDBM_File. Regardless, I think those are just fine for smaller apps. For apps with a lot of concurrency or application interactions, maybe a real database is better. It depends. Few solutions are right for all problems. That's part of the reason there's more than one way to do it.

Thanks for you reply. Actually, I have not used DB_File.

I use dbmopen(), dbmclose() like follows,

#!/usr/bin/perl
 
use strict; 
use warnings; 

my %hash; # To open a dbmfile and associate with hash 
dbmopen(%hash, "nagalenoj", '0666') || die "Can't open database file!"
+; 

$hash{'one'}="1"; 
$hash{'two'}="2"; 
$hash{'three'}="3"; 

#Retrieving values 
print $hash{'three'};

dbmclose %hash;

Hmmm... I wonder if the Applied Research Lab of the Washington University in St. Louis got permission from the copyright holder, O'Reilly & Associates, to host The Perl CD Bookshelf on its website. I doubt it...
