I am experimenting with editing JUST THE ATTRIBUTES of a feature class in SDE. I created a view in SQL Management Studio that had only the attribute fields (no shape, no objectid). Then I linked to that in MS Access using ODBC, and edited a few existing records through a form. The form is limited to edits (no additions or deletions available), and I have hidden the table from view. Hoping this might provide a better method for data entry than editing rows in ArcMap.
