RM depends on algebra if you like, set theory if you prefer. My comments about "adjacency" aren't meant to imply physical location, just an untyped (because supposedly universal) association. But "association" has too many connotations to use as the term, either. I might make the same protest against set theory itself, if set theory made the same pretense at domain representation that RM does. But everyone knows set theory is a low-level, if powerful (maybe even universal) tool. If that's all you see in RM, then fine. But I look at the idea of a normalized data model, and see an attempt to do something above and beyond a raw set theory, and in this attempt, it could use some new thinking, features, enhancements, extensibility, whatever.
