Scott Ambler, award-winning author of Building Object Applications that Work, Process Patterns, and More Process Patterns, has revised his acclaimed first book, The Object Primer. Long prized by both students and professionals as the best introduction to object-oriented technology, this book is now completely up-to-date, with all modeling notation rewritten in the just-released UML 2.0. All chapters have been revised to take advantage of Agile Modeling (AM), which is presented in the new chapter 2 along with other important new modeling techniques. Review questions at the end of each chapter allow readers to test their newly acquired knowledge. In addition, Ambler takes time to reflect on the lessons learned over the past few years by discussing the proven benefits and drawbacks of the technology. This is the perfect book for any software development professional or student seeking an introduction to the concepts and terminology of object technology.
