Choice for what? The article talks about a very specific domain (web applications solving a certain class of problem). Many organizations use multiple data stores and handle different problems. At Goldman Sachs there is almost every imaginable type of data store in use. All carefully vetted decisions that are largely the right choice much of the time. Almost all of it flows into some form of web application at some point in time in a giant interconnected system. I am very happy we don't use a single class of data store. If we did we'd be fucked. The "thesis" may apply very narrowly to a small web app of a certain size. But honestly if you are building something that cookie cutter are you really building something unique? What you are doing has probably been commoditized.
