It's all very well talking about data records. It's quite another thing with that "other stuff". I expect they'll dream up some polymorphic OO scheme, where objects provide their own management API. As for merging an "apple" with an "orange", it makes no sense. MERGE can only function on things where MERGE is rational. The problem then becomes - is the Astoria team rational! I see what you mean.

How should I merge two JPG images? How should I merge two timestamps? How should I merge two sonnets? Even if they can be defined in some way, how should I merge a JPG image with the result of merging a sonnet and a timestamp? Madness! My point really is that it can never be fully defined.

Madness!

UPDATE works in the SQL area, presumably because it is defined. Would you be satisfied if MERGE were well defined, or is that not possible?
