Service Patterns and Anti-Patterns
Microsoft’s John Evdemon has written an interesting article entitled Principles of Service Design: Service Patterns and Anti-Patterns.
In the article, he mentions two anti-patterns, the first being a web service interface that is too fine grained and the second is a too generic interface with no real service contract. He also lists three patterns, which show document-based communications, idempotent messages, and reservations.
Even though the patterns mentioned in the article are not as good as those in Enterprise Integration Patterns, it still is an interesting read.
