Query: Just an overview

Well, any dax related book is welcomed since we don't have many.It's not that the books is bad for its purpose, but like the other negative reviewers say, it's just a general overview book that is not enough to scrape the surface of it and that is the truth. Someone should come up with sceries of books that concentrate on a module at a time.So, if you are expecting too much and in a situation of doing dirty practical hands-on stuffs...working with MorphX and X++ through the maze of classes, data dics, forms, etc, you shouldn't expect too much from it.
