This is a very interesting blog entry for me ! Because I'm considering to use native XML DBs with XQuery and/or OODBMSes and/or Kris Zyp's Persevere (uses JSONQuery). Since I'm no expert DB practioner, please allow me to ask the following questions: - You state "NoSQL systems either use a new declarative language that is much less powerful than SQL": Does this mean that SQL is more powerful than XQuery, JSONQuery, or Query Languages for OODBMSes ? - One main reason for me to use native XML DBs and/or OODBMSes is: Avoidance of ORM; what's Your take on this important topic ? Cheers and Tschüss Kai (Tischler) from Northrhine-Westfalia in Germany Hello Jeff !
