Yes, "SOA: Principles of Service Design" is a great book, I agree. It had to be more technical than Steve's book because the latter targeted wider understanding of the services based on the SO principles. However, Erl's book was written in 2006/07 and published on July 28, 2007, i.e. 6 months after OASIS SOA RM standard was issued.
SOA Design Patterns is published in 2009, when OASIS SOA RM is known for long enough to understand (accept or deny) that Service Inventory is not a pattern of service orientation, it is a pattern of technology inventory, IMO. - Michael ________________________________ From: Kirstan Vandersluis <[email protected]> To: [email protected] Sent: Friday, January 16, 2009 12:10:15 AM Subject: [service-orientated-architecture] Re: Vaughan reviews Erl's Tome --- In service-orientated- architecture@ yahoogroups. com, Michael Poulin <m3pou...@.. .> wrote: > > ... > I have a feeling that represented SOA Design Patterns are not really patterns of SO design but any patterns where Web Services were or may be used. This means that SOA obfuscation with Web Services continues... I've read Erl's previous book, SOA: Principles of Service Design, and was impressed with it's well-rounded treatment of issues in the design of services. Erl's definition of a service is more technical in nature than Steve Jones' in his book, but it is far from a cookbook for mere web services. In fact, I would highly recommend it for anybody implementing services. Personally, I'm interested in giving Erl's new book a read also, if I can ever find the time! -Kirstan
