A data is not relational or not-relational. Creating relations is a way to model data. Sometimes it's adequate, sometimes it's not. As for the separation between "static" and "dynamic", again, I'm not sure I follow you. The definition of what is static and dynamic depends on how your model the data. What if you store every update? What is static? What is dynamic? Is new content dynamic or static? Additionally, do you imply XML or JSON may be valid to store, say, a HD movie?
