Let's rewrite the microservices wiki as bit:

"A microdata architecture – a variant of the data-oriented architecture structural style – arranges data as a collection of loosely-coupled data. In a microdata architecture, data are fine-grained and the relations are lightweight."

Likely most experienced data architects are now laughing at what a dumb idea the above is. That's the same reaction I had when I first heard of microservices - "that's obviously a bad idea; ppl aren't that dumb", I thought.
