class, you should probably use L<DBIx::Class::DB> directly instead.

+carefully as DBIx::Class does things a little differently. Note in

well as subclasses for each of your database classes in this namespace, using
this connection.
+It will also setup a ->table method on the target class, which lets you
+resolve database classes based on the schema component name, for example
+
+ MyApp::DB->table('Foo') # returns MyApp::DB::Foo,
+ # which ISA MyApp::Schema::Foo
+
+This is the recommended API for accessing Schema generated classes, and
+using it might give you instant advantages with future versions of DBIC.
