This page provides links to my books and web-based writings.   Over the years I have published a fair bit of information, some of which is contradictory (although the advice fits the context), on several sites.  I have information posted at Agile Data, Agile Modeling, Ambysoft, Computing Canada, Enterprise Unified Process^TM, IBM DeveloperWorks, Oracle Technology Network, and Dr. Dobb's Journal Online.  The articles posted at DDJ are marked with the icon and the articles at IBM Developerworks with the icon.  I also have an Agile Modeling newsletter via DDJ and my Agile at Scale blog at IBM Developerworks.
