Are you familiar with the work by one Nikos Lorentzos ? I have a book in my library that was published 2003, summarizing his approach.

And since you claim that your solution is "complete", I reckon you also know what to do about and how to deal with, say, cyclic point types ?

Wait a sec. Just because you allow only additions in your databases, implies that it is impossible to have redundancy in your databases ?

"Closed WORLD assumption", anybody ?
