For data representation, I agree completely. But I think of UIs and reports as forms of data extracts: they're restricted and (typically, but not always) tree-structured "views" of a subset of a database. The power of relational for shared databases is in part its ability to support arbitrary extracts of the data in an egalitarian fashion - no application bias. Any given UI or report includes a set of (typically key-related) restrictions and projections across different relations. It appears to me (and I could be wrong, as this is only a pet hypothesis at this point) that expression languages to derive these would be tree-structured, or at least would be different than a relational algebra or calculus.

In fairness, it wasn't Dawn who introduced the term. I thought maybe it had a meaning, but suspect it doesn't. Agreed that the O-O folks don't have a consensus on this, nor is it critical in the discussion of data.
