SOA en-us Copyright 2006-2008, SOA Systems Inc. http://www.soamag.com/I15/0208-3.asp Integration is a concept that changes with the adoption of a service-oriented architecture. Whereas in silo-based environments, programs had to be explicitly connected using technologies and strategies to overcome incompatibilities, with SOA, connectivity is a characteristic you build into each service. This article explores how integration can be approached with the support of SOA via the use of process-centric design techniques that help separate service logic into layers that form a service stack, thereby estabalshing natural, cross-layer service composition designs.
