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?
