[VPM] Fwd: [reccompsci] Re: Impending mtg. Call for talks. (fwd)

[Peter Scott]

Although my schedule doesn't permit me to attend tomorrow evening, this 
looks like a very interesting talk and one I am happy to forward to 
Victoria.pm.

>Set::Relation provides a simple Perl-native facility for an application to
>organize and process information using the relational model of data, without
>having to employ a separate DBMS, and without having to employ a whole
>separate
>sub-language (such as Muldis Rosetta does).  Rather, it is integrated a lot
>mor
>e
>into the Perl way of doing things, and you use it much like a Perl array or
>hash, or like some other third-party Set:: modules available for Perl.
>This is
>a standalone Perl 5 object class that represents a Muldis D quasi-relation
>value, and its methods implement all the Muldis D relational operators.
>
>A simple working example:
>
>      use Set::Relation;
>
>      my $r1 = Set::Relation->new( members => [ [ 'x', 'y' ], [
>          [ 4, 7 ],
>          [ 3, 2 ],
>      ] ] );
>
>      my $r2 = Set::Relation->new( members => [
>          { 'y' => 5, 'z' => 6 },
>          { 'y' => 2, 'z' => 1 },
>          { 'y' => 2, 'z' => 4 },
>      ] );
>
>      my $r3 = $r1->join( $r2 );
>
>      my $r3_as_nfmt_perl = $r3->members();
>      my $r3_as_ofmt_perl = $r3->members( 1 );
>
>      # Then $r3_as_nfmt_perl contains:
>      # [
>      #     { 'x' => 3, 'y' => 2, 'z' => 1 },
>      #     { 'x' => 3, 'y' => 2, 'z' => 4 },
>      # ]
>      # And $r3_as_ofmt_perl contains:
>      # [ [ 'x', 'y', 'z' ], [
>      #     [ 3, 2, 1 ],
>      #     [ 3, 2, 4 ],
>      # ] ]
>
>This talk will focus on describing the features of Set::Relation, discussing

>y
>in your program that you might otherwise offload to a SQL DBMS or other

>and will go into detail on how the module is designed and works, including a
>source code walk through.  The talk will also shed some light on other
