Martin, > Third Normal >From the chapter on Normalization in some very large book about Oracle: "No non-trivial system will ever exist using 3rd normal form." :) I share your concerns about the data living in multiple places. However, the users want direct feedback about validation errors... Not just the error message, but some visual feedback as well - a link that places them in the offending field, or some highlighting around the field. The problem is that our validation logic has no knowledge of the visual layer (which is what we want), and our visual layer can be either a Swing GUI or a web page. An error message that makes perfect sense in the web world may not in the Swing GUI and vice versa. Thanks!
