Specialized SOA Design Patterns
In this second podcast dedicated to SOA design patterns, author Thomas Erl focuses on a set of specialized service design patterns to demonstrate how they can be applied together. The Service Decomposition pattern is explained first, followed by the related Proxy Capability pattern and then the Decomposed Capability pattern which can be applied in advance in support of post-implementation service decomposition.
