It works great, but you throw away the diagrams and just use the sentences after awhile. What drives people nuts is that it takes longer to do ORM than to splash up an ER diagram. But you will get it right, which is not guaranteed by ER.
Terry is working on a second book on how to use the Visio tools, but I do not know the expected publication date. Received on Sun Sep 29 2002 - 22:07:57 CEST
