To all the brilliant people who came up with various ways to gather requirements, analyze software, and design code...

...thanks for coming up with something good enough to produce great software, but hard enough that we needed this book to explain it all.

Praise for Head First OOA&D

Head First Object-Oriented Analysis and Design is a refreshing look at the subject of OOA&D. What sets this book apart is its focus on learning. There are too many books on the market that spend a lot of time telling you why, but do not actually enable the practitioner to start work on a project. Those books are very interesting, but not very practical. I strongly believe that the future of software development practice will focus on the practitioner. The authors have made the content of OOA&D accessible and usable for the practitioner

I just finished reading HF OOA&D , and I loved it! The book manages to get across the essentials of object-oriented analysis and design with UML and use cases, and even several lectures on good software design, all in a fast-paced, easy to understand way. The thing I liked most about this book was its focus on why we do OOA&Dto write great software! By defining what great software is and showing how each step in the OOA&D process leads you towards that goal, it can teach even the most jaded Java programmer why OOA&D matters. This is a great first book on design for anyone who is new to Java, or even for those who have been Java programmers for a while but have been scared off by the massive tomes on OO Analysis and Design.

Kyle Brown, Distinguished Engineer, IBM

Finally a book on OOA&D that recognizes that the UML is just a notation and that what matters when developing software is taking the time to think the issues through.

Pete McBreen, Author,Software Craftsmanship

The book does a good job of capturing that entertaining, visually oriented, Head First writing style. But hidden behind the funny pictures and crazy fonts is a serious, intelligent, extremely well-crafted presentation of OO Analysis and Design. This book has a strong opinion of how to design programs, and communicates it effectively. I love the way it uses running examples to lead the reader through the various stages of the design process. As I read the book, I felt like I was looking over the shoulder of an expert designer who was explaining to me what issues were important at each step, and why.

Edward Sciore, Associate Professor, Computer Science Department Boston College

This is a well-designed book that delivers what it promises to its readers: how to analyze, design, and write serious object-oriented software. Its contents flow effortlessly from using use cases for capturing requirements to analysis, design, implementation, testing, and iteration. Every step in the development of object-oriented software is presented in light of sound software engineering principles. The examples are clear and illustrative. This is a solid and refreshing book on object-oriented software development.

By starting with simple concepts and examples, the book gently takes the reader from humble beginnings to (by the end of the book) where the reader should be comfortable creating Ajax-based websites... Probably the best web designer centric book on Ajax.

Stefan Mischook, Killersites.com

Using the irreverent style common of the Head First / Head Rush series of books, this book starts at the beginning and introduces you to all you need to know to be able to write the JavaScript that will both send requests to the server and update the page with the results when they are returned... One of the best things about this book (apart form the excellent explanations of how the code works) is that it also looks at security issues... If you learn Ajax from this book you are unlikely to forget much of what you learn.

Stephen Chapman, JavaScript.About.com

Head Rush Ajax is the book if you want to cut through all the hype and learn how to make your web apps sparkled...your users will love you for it!

Kristin Stromberg, Aguirre International

If you know some HTML, a dollop of CSS, a little JavaScript, and a bit of PHP, but youre mystified about what all the Ajax hype is about, this book is for you... Youll have a blast learning Ajax with Head Rush Ajax . By the time youve reached the end of the book, all those web technologies that didnt quite fit together in your head will all snap into place and youll have The Ajax Power! Youll know the secrets behind some of the most popular web applications on the Internet. Youll impress your friends and co-workers with you knowledge of how those interactive maps and web forms really work.

Elisabeth Freeman, The Walt Disney Internet Group Co-Author, Head First Design Patterns and Head First HTML with CSS & XHTML

If you thought Ajax was rocket science, this book is for you. Head Rush Ajax puts dynamic, compelling experiences within reach for every web developer.

This stuff is brain candy; I cant get enough of it.

My wife stole the book. Shes never done any web design, so she needed a book like
