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.
