NAME

         Data::Stag::StagDB - persistent storage and retrieval of stag nodes

SYNOPSIS

         # parsing a file into a file based index
         my $sdb = Data::Stag::StagDB->new;
         $sdb->unique_key("ss_details/social_security_no");
         $sdb->record_type("person");
         $sdb->indexfile("./person_by_ss-idx");
         Data::Stag->parse(-file=>$fn, -handler=>$sdb);
         my $obj = $sdb->index_hash;
         my $person = $obj->{'999-9999-9999'};
         print $person->xml;

         # indexing an existing stag tree into a file based index
         my $personset = Data::Stag->parse($fn);
         my $sdb = Data::Stag::StagDB->new;
         $sdb->unique_key("ss_details/social_security_no");
         $sdb->record_type("person");
         $sdb->indexfile("./person_by_ss-idx");
         $personset->sax($sdb);
         my $obj = $sdb->index_hash;
         my $person = $obj->{'999-9999-9999'};
         print $person->xml;

DESCRIPTION

       This module is an extension of Data::Stag::HashDB - you can use it in the same way.

       It creates a simple file based database of stag nodes

       This is useful if you want your data to persist; or if you want to use Data::Stag::HashDB
       but your data will not fit into memory
