1.9 Recommended Resources
Various OOA/D texts are recommended in later chapters, in relation to specific subjects, such as OO design. The books in the history section are all worth studyand still applicable regarding their core advice.
A very readable and popular summary of essential UML notation is UML Distilled by Martin Fowler. Highly recommended; Fowler has written many useful books, with a practical and "agile" attitude.
For a detailed discussion of UML notation, The Unified Modeling Language Reference Manual by Rumbaugh is worthwhile. Note that this text isn't meant for learning how to do object modeling or OOA/Dit's a UML notation reference.
Visual UML modeling in an agile modeling spirit is described in Agile Modeling by Scott Ambler. See also www.agilemodeling.com.
There are many books on software patterns, but the seminal classic is Design Patterns by Gamma, Helm, Johnson, and Vlissides. It is truly required reading for those studying object design. However, it is not an introductory text and is best read after one is comfortable with the fundamentals of object design and programming. See also www.hillside.net and www.iturls.com (the English "Software Engineering" subsection) for links to many pattern sites.
