Answer 1

Actually laravel transaction can do in two ways

First Method: Handle transaction and rollback on you requirements

try {

   DB::beginTransaction();
   //Db trnscations
} catch (\Exception $e) {
   DB::rollBack()
}

Second Method: It will handle transaction and rollback it self

DB::transaction(function () {

});

Answer 2

It's absolutely the same, because you're calling transaction() method on \\Illuminate\\Database\\Connection object. These are just different approaches how you access Connection object, either through DB facade or through a model class.
