Nahh perfect would have been if they hat stopped at: Technically, any database could support SQL as a language
Or even added: , but what we are really talking about is half finished databases with limited capabilities that happen to suite a specific need. The reality is SQL is in no way a limitation on a database design, however by lowering the bar you can build a useful prototype which at some point might become a database. And then gone on to describe an actual problem with an interesting solution.
They are not half finished databases (ok, some of them are), they are just databases that operate under a different set of constraints and optimize accordingly.
