Yep I too was quite disappointed by this. The article contained a lot of bombast about giving up on SQL and taking the opportunity to do some blue-sky thinking about creating a better API for 'structured data'. I was hoping this meant they were going to replace SQL with a more modern relational API, correct some of the flaws in SQL while they're at it and base it truly on the relational algebra. Turns out it's just yet another souped-up key-value store, or 'hierarchical database'. No joins, no real relational functionality to speak of. I thought we already had a client-side key-value store API? If only people would actually read some of the theory on relational databases before eagerly reinventing a square wheel. </old fart before his time>
