It's really very impressive - can't wait for Date's book on TransRelational,

Me too, I am implementing the basic idea in my spare time, but using a
sligthly different approach also appropriate to be used in disk based
DBMS's.
The little I know about it comes from Intro to DB Systems 8th edition,
but that doesn't cover (as I think someone else said earlier in this
thread) how TransRelational deals with inserts, updates and deletes.
If each I, U or D requires a rejigging of the TR tables underlying
virtually every record in the database table, that sounds like a lot
of work doesn't it? Or does anyone know how it avoids that?

See the patent text.

There are multiple ways to avoid that,but the one I like more is to
use B+Trees or B*Trees.
