I'm looking at some of the comments and still having a little bit of trouble understanding what makes the data engine "universal."

I see reference to "universal storage" in some areas, but keep landing on a multi-dimensional array structure for data storage - and this seems kind of at odds. Maybe I'm missing something, but isn't specifying the structure of the data inherently not universal?

I'm relatively shielded in my databases knowledge, though - having only worked with "traditional" tools. If I'm missing something definitely let me know!
