This general applicability to all languages is what makes patterns so powerful. In their book, they use C++ and Smalltalk however, the book is geared to the patterns themselves, and not the language used to implement them. Besides Christopher Alexander, who first spoke of design patterns when referring to the actual architecture of buildings, the Gang of Four's work represents some of the original thoughts on object-oriented design patterns. Like the "three amigos" of UML (Grady Booch, James Rumbaugh, and Ivar Jacobson), these four began the work of forming what is now thought of as the standard patterns. One of the better places to start learning about patterns is with the "Gang of Four"-Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides, authors of Design Patterns.

But first we must explain the patterns themselves. It will provide the ability to answer and route online product support questions effectively and efficiently.

(No, it is not another purchase order or reservations code sample!) The sample application will show how applying patterns to BizTalk can significantly ease the development and design for each subdepartment.

Our sample implementation, available for download from the link at the top of this article, focuses on a product support department. In addition, we'll even point out a few patterns that BizTalk itself uses. Finally, we will implement each pattern in the context of the BizTalk Orchestration Designer and put the patterns to work in a custom way. We will also refer to other related patterns such as Interface, Factory Method, and Delegation. Recognizing them not only helps improve your own custom design, but it also helps explain an existing implementation, whether this implementation is custom code you must now support or a commercial application such as BizTalk. We hope to show how traditional design patterns can be seen and utilized in any design, or in any technology. In this article we will take some of the more traditional object-oriented design patterns, such as the Observer pattern, and use them in slightly different ways, while still keeping their behavioral benefits intact. In fact, design patterns have traditionally been associated with purely object-oriented languages. This is not to say that these patterns only apply to BizTalk or any particular implementation.

We'll show you how to use these patterns in such a way that they can be applied to a loosely coupled architecture as one implemented with BizTalk™. We'll do the same with one of our own patterns, called the Dispatcher.

In this article, we will explain and implement the Observer and Chain of Responsibility patterns adapted from the book Design Patterns: Elements of Reusable Object- Oriented Software (Addison-Wesley, 1995). It is the standardized and fossilized assemblage of those UML symbols we need, and all of the historical toil that has gone along with those assemblies. UML helps, but it really only contains the hieroglyphics (or language) you may need to convey your design. If you are thinking about Unified Modeling Language (UML), you are close, but not quite there. How do you learn to approach existing designs in a new way? And once you have a good design, how do you make it reusable? An even better question is how do you reuse what others have struggled to perfect? Most great designs aren't developed on the first attempt they must go through stages of change before they can be considered valuable. In fact, a great design with older technology may still be good, but a bad design with new technology is usually just bad. And no matter how good the technology may be, it is only as good as its design, and specifically the implementation of that design. Hen it comes to software design, a good design is a good solution regardless of the technology. Following this is a discussion on using the BizTalk Orchestration Designer to build designs and integrate existing business processes. This article describes several traditional design patterns including the Observer pattern and the Dispatcher pattern, elaborates on their structures, what they're used for, and how they can help you build a BizTalk-based solution. SUMMARYBecause the value of good software planning and design should never be underestimated, it can be beneficial to use one of the many existing design patterns as a foundation for solving some of your toughest architecture problems.
