If you have technical questions or error reports, you can send them to booktech@oreilly.com. Please specify the printing date of your copy. This page was updated June 15, 2007. Here's a key to the markup: [page-number]: serious technical mistake {page-number}: minor technical mistake : important language/formatting problem (page-number): language change or minor formatting problem ?page-number?: reader question or request for clarification Confirmed errors: (2) 6th paragraph; Last sentence of paragraph: If a particular diagram helps you convey your message you should use it; this is one of the basic tenants of UML modeling. The word "tenants" should be replaced with "tenets". (24) Last paragraph, line 3; "Each of UML relationship" should be "Each UML relationship" [28] Last line on page; Mistaken choice of word: "UML allows for multiple inheritance, meaning a class can have more than one generalization with each representing an aspect of the decedent class." **decedent** should be "descendant".
