I think he&#x27;s saying his main point, though, is that storing objects in a RDBMS using OR-mapping is a pain in the ass and there will be better ways to do it. With the advent of NoSql DBs, and the number of DBs that store their data in JSON, I think this is largely correct. Back in 2004, XML was largely shorthand for &quot;serialized object&quot;. He was wrong about the serialization format, but right about the overall idea.
