You know nothing about software architecture if you think that you can't optimize a software performance/responsiveness changing the way you store/normalize/retrieve data.
I know that I wouldn't want the choice of a fly-by-night front-end framework influencing how that's done with a back-end database. But, looks like I made the wrong assumption about the db structure that was influenced, I guess we have front-end databases now, which is an interesting idea I will be exploring furtherer.
