Product Description

Design patterns offer proven opportunities for creating flexible, reusable software -- but until now, their complexity has prevented most software professionals from taking full advantage of them. Now, there's a simple, gentle introduction to patterns that helps software practitioners gain the benefits -- without the confusion. Unlike many books on patterns, Design Patterns Explained doesn't assume that its readers already have an in-depth understanding of object-oriented design. Rather, it teaches object-oriented design and patterns together, helping developers gain deeper insights into both topics far more quickly. Shalloway and Trott don't just introduce a laundry list of patterns: they explain why each pattern works, the organizing principles upon which the pattern is based, and above all, how the patterns work together in real world object-oriented designs. For all software developers, programmers, architects, and project managers who want to succeed with patterns.

From the Back Cover

"...I would expect that readers with a basic understanding of object-oriented programming and design would find this book useful, before approaching design patterns completely. Design Patterns Explained complements the existing design patterns texts and may perform a very useful role, fitting between introductory texts such as UML Distilled and the more advanced patterns books."--James Noble

Design Patterns Explained: A New Perspective on Object-Oriented Design draws together the principles of object-oriented programming with the power of design patterns to create an environment for robust and reliable software development. Packed with practical and applicable examples, this book teaches you to solve common programming problems with patterns--and explains the advantages of patterns for modern software design.

Beginning with a complete overview of the fundamentals of patterns, Design Patterns Explained stresses the importance of analysis and design. The authors clearly demonstrate how patterns can facilitate the overall development process. Throughout the book, key object-oriented design principles are explained, along with the concepts and benefits behind specific patterns. With illustrative examples in C++ and Java, the book demystifies the "whys," "why nots," and "hows" of patterns and explains pattern implementation.

Key topics covered include:

New perspectives on objects, encapsulation, and inheritance
The idea of design patterns, their origins, and how they apply in the discipline of software design
Pattern-based, object-oriented software development using the Unified Modeling Language (UML)
How to implement critical patterns--Strategy, Observer, Bridge, Decorator, and many more
Commonality/Variability Analysis and design patterns, and how they aid in understanding abstract classes

From analysis to implementation, Design Patterns Explained allows you to unleash the true potential of patterns and paves the path for improving your overall designs. This book provides newcomers with a genuinely accurate and helpful introduction to object-oriented design patterns.

4.0 out of 5 stars Good introduction to pattern usage and implementation., 17 Sep 2001

By A Customer

If you've found the GoF book too abstract or don't yet have suficient experience recognising the problems that pattern solutions have been devised for then this is a good place to start. The book takes a very gentle pace - but does a good job of explaining a number of the GoF patterns. The style is very 'training material' like - which it may have been originally, you get told what you're going to be told/learn - then you get told it - then you are reminded of what you've just been told. This can feel a little over the top in a book - but, hey!, there's really no competition for this book out there.

It certainly acheived it's aim for me - I can now make sense of the other pattern books.

5.0 out of 5 stars Highly Recommended, 11 Sep 2003

By	J Kavanagh (Hampton, Middlesex United Kingdom) - See all my reviews

Coming from an OO background I'm relatively new to the concept of patterns. I'd bought the GOF bible but the coverage of some of the patterns therein was extremely difficult to understand.

This book takes time out to explain the motivations behind Alexanders' original book which was the inspiration for the GOF. This part I found both engrossing and inspiring (extremely unusual for a book of this sort! :)).

It goes on to give tangible examples, explained in-depth and although (as others have commented) it doesn't cover all the patterns detailed in the GOF bible, it does give you a solid grounding from which you can accelerate your learning curve.

After reading I've found it much easier to analyse a particular problem and decide which patterns to apply to great effect.

Well done Alan and James!

5.0 out of 5 stars Want to understand basic patterns? Buy this book., 11 Jun 2003

By	Mr. I. Roberts "Ian Roberts" (UK) - See all my reviews (REAL NAME)

Prior to purchasing this book I had attended a OOAD course, explaining basic patterns, and studied a number of books that included the GoF "bible", so I already had a basic understanding of design patterns. However, what makes this book very good is that from all the books I have read this one offers the best introduction into world of OO design patterns.

Although the book explains the very basic patterns, its purpose is to teach you how to understand patterns so that the concept applied at understanding the ones within the book can be used to understand the more complicated ones.

I only wish I had bought this book before buying the more reference type books because I would have saved myself a lot studying time.

This book is aimed at those that want to start to understand the design pattern concept, although it can also be used as a reference book for the limited patterns explained.
