We talk about the missing information/nulls/unknown values problem all the time here. We talk about it and talk about it. But we never talk about the transitive closure issue. Why is that? Is it a solved issue for many of us?

The transitive closure issue seems like a bigger issue than
the missing values issue. What are the possible solutions?
What's good and bad about them?
What about TTM's proposed TCLOSE?
What about a Prolog-like solution?
What about recursive queries?
Comments/Comparisons/Complaints? Experiences?
