Roger,
All false, and demonstrably so.
Everything you cited is handled today (and has been for years) by
relational database systems. We can argue about whether that is the most
"appropriate" (whatever that means) mechanism, but it certainly does it
and does it pretty well. Would use of a different model (e.g., RDF et
al) provide significant advantages? Probably. Would it offer significant
disadvantages. Undoubtedly.
It feels to me that you continue to seek silver bullets. There are no
silver bullets, only tools of varying degrees of appropriateness and
varying degrees of pain (often inversely proportional).
Hope this helps
Jim

You have data about the destination and originating points of the aircraft. You have data about the passengers on the aircraft. And you have many other chunks of relevant data. And, the relationships between all these chunks of data must be captured.
