This book, meant to serve as a textbook on the subject, provides a comprehensive introduction to OOAD. The salient points of its coverage are:

• A sound footing on object-oriented concepts such as classes, objects, interfaces, inheritance, polymorphism, dynamic linking, etc.
  
• A good introduction to the stage of requirements analysis
  
• Use of UML to document user requirements and design
  
• An extensive treatment of the design process
  
• Coverage of implementation issues
  
• Appropriate use of design and architectural patterns
  
• Introduction to the art and craft of refactoring
  
• Pointers to resources that further the reader's knowledge

The book stresses on implementation aspects, without which learning is incomplete. This is achieved through case studies. The case study of a library system is carried through most of the book, and it is using this that the various concepts of analysis and design are introduced. Thus, the theory is never separate from the implementation aspect and hence the learning is more meaningful. All the main case studies used in this book have been implemented by the authors using Java. The text is liberally peppered with snippets of code, which are short, fairly self-explanatory and easy to read. The appendix on Java has a short tutorial on the language, which is a quick guide to understanding the implementation aspects of the code in the book.
