Implementation and theory aren't the correct distinction here. A data model obviously must be implementable. A transactional model must be implementable. And any data model can't prevent the implementation of transactions. How that makes data model and transactions one and the same you failed to demonstrate.
Seems to me you never read Date, Darwen, Codd, McGoveran & Pascal with any profit. Your posts are full of misinformation, with no usefulness at all. Sorry.
