DBMS(3)		      User Contributed Perl Documentation	       DBMS(3)

NAME
       DBMS - Perl5 access to a	dbms server.

SYNOPSIS
	   use DBMS ;
	   $x=tie %hash, 'DBMS', $type,$name;

	   # Use the %hash array.
	   $hash{ aap }	= noot;
	   foreach $k (keys(%hash)) {
	       print "$k - $hash{ $k }\n";
	       };
	   # and destroy..
	   undef $x;

DESCRIPTION
       DBMS is a module	which allows Perl programs to make use of the
       facilities provided by the dbms server. The dbms	server is a small
       server with a bit of glue to the	Berkeley DB (> 1.85 < 2.x) and some
       code to listen to a few sockets.

DETAILS
       As the devil is in the details... this module supports three functions
       which are not part of the normal	tie interface; atomic counter
       increment, atomic counter decrement and atomic list retrival.

       The increment and decrement functions increments	or decrement a counter
       before it returns a value. Thus a null or undef value can safely	be
       taken as	an error.

   EXAMPLE
	   use DBMS ;
	   $x=tie %hash, 'DBMS', $type,$name
	       or die "Could not ty to $name: $!";

	   $hash{ counter } = 0;

	   $my_id = $x->inc( 'counter' )
	       or die "Oi";

	   $my_id = $x->dec( 'counter' )
	       or die "Oi oi";

	   # and these are not quite implemented yet..
	   #
	   @keys = $x->keys();
	   @values = $x->values();
	   @all	= $x->hash();

AVAILABILITY
       Well, ah	hmmm. For ParlEuNet at the beginning but now for the whole
       CPAN community.

BUGS
       Memory management not fully checked. Some speed issues, I.e. only about
       100 TPS.	No proper use of $! and	$@, i.e. it will just croak, carp or
       return an undef.	And there is no	automagic retry	should you loose the
       connection.
