Create fake DB from laravel seed

I want to create DB with fake data without using any migrations.

my tables are divided into two types.

Tables with model : This I know their solution with use faker and model class like this example :

        $user->posts()->save(factory(App\Post::class)->make());
    });

Tables without model : I don't know how I can use DB facade to create tables and generate same fake data in the same time
