"It looks and behaves like a traditional SQL database from the outside but under the covers it's a revolutionary database solution."
Doesn't tell me a whole lot. Please explain what is revolutionary about it.
Quite frankly, as a developer, I prefer to use flat files (I guess these days we call that NoSQL), but for performance, I often must use Postgres or whatever fits the job.
