That's my way ATM:

1. Data definition for MySQL in plain ASCII (because I'm used to it)
2. use the DBIC::Schema Catalyst helper to build the schema classes
3. overhaul the created schemas
4. write a tiny deploy script:

use FindBin;
use lib "$FindBin::Bin/../lib";

use MyApp::Schema;
use MyApp::Util::Script qw(load_config);

my $config = load_config;
my $schema = Coreg::DB->connect(@{$config->{'Model::DB'}->{connect_info}})
    or die "unable to connect\n";

# deploy directly

# or if you want it as DDL:
my $sqldir = "$FindBin::Bin/../sql/";
$schema->create_ddl_dir(['MySQL', 'SQLite', 'PostgreSQL'], '0.1', $sqldir);

The question is: "Recommended by whom?" TIMTOWTDI as always.
