"I really question your experience with databases. " I have used SQL Server, Oracle, MySQL, SQLite, MS Access(!), Sybase and ... CouchDB! I have optimized queries in SQL Server and Oracle. Most of them commercially (not CouchDB). "Because blindly grouping all SQL databases together is a sure fire way to get yourself into a world of trouble. They don't store data the same way. They all have subtle differences in their support for the standards. They all have proprietary features. And their operational characteristics couldn't be more wildly different." Spot on. Not sure how it relates to my post.
