NAME

       TM::Materialized::MLDBM2 - Topic Maps, DBM Storage (synchronous)

SYNOPSIS

          NOTE: THIS PACKAGE IS NOW DEPRECATED
          NOTE: USE TM::ResourceAble::MLDBM INSTEAD

          use TM::Materialized::MLDBM2;
          {
           my $tm = new TM::Materialized::MLDBM2 (file => '/tmp/map.dbm');
           # modify the map here.....

           } # it goes out of scope here, and all changes are written back automagically

          # later in the game
          {
           my $tm = new TM::Materialized::MLDBM2 (file => '/tmp/map.dbm');
           # we are back in business, no sync necessary
           }

DESCRIPTION

       This package just implements TM with a BerkeleyDB store. Unlike TM::Materialized::MLDBM this module does
       not need explicit synchronisation with the external resource (the DBM file here).  It ties content-wise
       with the DBM file at constructor time and unties at DESTROY time.

       The advantage of this storage form is that there is little memory usage. Only those fractions of the map
       are loaded which are actually needed. If one has very intense interactions with the map (as a query
       processor has), then this storage technique is not optimal.

INTERFACE

   Constructor
       The constructor expects a hash with the following keys:

       file (no default)
           This contains the file name of the DBM file to tie to.
