Some thoughts:
- you use the word "relation" in the sense of "relationship", and not
in the relational sense ("relation" ~= "table"), which could be
confusing
- why "physical" data elements? Integrity is logical surely?
So perhaps, and with additional simplifications:
A2: A measure of the consistency of the relationships between the data elements defined in a database. Received on Thu May 19 2005 - 14:55:37 CEST
