The newest design you’ve said given that a presentation are an effective Kimball-modelled dimensional design; it is an ideal design in every senses of one’s phrase. It has to possess undoubtedly sophisticated show services (this is the fastest solution to model studies in almost any regular database). Not one person conflicts this (possibly the Study Vault people use dimensional patterns because their speech layer). But really it entails bi-directional filtering be effective and you also say , “In the event your model need the latest one another-directional relationships from the most the newest matchmaking, your design isn’t designed better.” In another post you probably believe that this is actually the most readily useful kind of design ( very that’s it – is a dimensional model the way to wade, in which case bi-directional selection is alright, or perhaps is here some other way we should be carrying it out? Absolutely you do not anticipate a cross-filter out DAX mode for each scale inside the an effective (probably higher) dimensional design. Who would defeat the objective of modelling like that.
