SOA Design Patterns and Design Principles

The design patterns in this catalog reference the following service-orientation design principles where appropriate to highlight a dependency or relationship or perhaps to describe the effect a design pattern may have on service-orientation (or vice versa):

Specifically, the potential relationship between service-orientation design principles and patterns can be summarized as follows:

  • Design principles are applied collectively to solution logic in order to shape it in such a manner that it fosters key design characteristics that support the strategic goals associated with service-oriented computing.
  • Design patterns provide solutions to common problems encountered when applying design principles-and-when establishing an environment suitable for implementing logic designed in accordance with service-orientation principles.

In many ways, design principles and patterns are alike. Both provide design guidance in support of achieving overarching strategic goals. In fact, it would not be unreasonable to think of the eight service-orientation principles as super patterns that are further supported by the patterns in this book.

Service-orientation design principles have another role in that they collectively define service-orientation as a design paradigm. Ultimately, it is best to view design patterns as providing support for the realization of design principles and their associated goals.
