Re: How to make RDBMS ?

D at B dot A,

Correct me if I'm wrong, but I think there are three different positions here:

Todd, who was saying that DB is inherently simpler than OS. You, who are saying DB is inherently more complex than OS, as current research is revealing.
And I, who regard them as being of approximately the same order of complexity.

The middle position isn't always the right position. But, in this case, I get certain comfort
from knowing that there are opinions on both sides of mine here.

Unless I've misunderstood you or Todd.
