I thought this question deserved its own thread. I have it on the back
burner to think about this one again. This is done in UIs, browser or
not, in a variety of ways. As much as I try to dispell the myths about
1NF being mathematically or otherwise better than non-1NF, displaying a
2D matrix on a computer screen is easier than shapes where there are
tables within tables. But whether you are using a relational model or
an xml or pick model, you will still have a need for this UI structure.

One option that I can't recall seeing used with a database, but which
is common with a file system is a tree structure for navigating. At
each node there is a 2D table where each cell is either a value or a
folder. Click on a folder to see another table, until you get to a
leaf node where every cell has a value -- no folders. This would be a
visual representation of a multivalued "view" of data (compared to a
SQL view of data).

Who has a good solution for the UI for nested tables? --dawn
