I think the responsibility of showing that data entered into RM implementations is not at the logical level falls on the shoulders of the people who say it doesn't and not upon me. They should also explanation which data entered in RM dbs is logical and which is physical and why. After all it is they who have been loudly proclaiming RM is a logical model and one would assume that most RM implementation provide a logical interface to data.
As for TM, I know that things (symbols, strings, etc) in the db can be implementated on various hardware, including a boundary consisting of sticks and stone and a human moving them around to simulate a processor. Received on Wed Jul 21 2004 - 01:24:40 CEST
