Graig,

>CursorAdapters don't work well in n-tier because they create a cursor. If the tiers are physically separated, you can't pass the cursors without converting them to something else (XML?).

>Also, if you currently are using RVs and the TABLEUPDATE() and other commands sit in the UI, then you DON'T have a good n-tier design.
