U.S. Pat & TM Off How is SOA different from messaging? A common practice in healthcare, just not yet in healthcare IT Many key products use them but do not expose interfaces Ensures functional consistency across applications Accepted industry best practice Furthers authoritative sources of data Minimizes duplication across applications, provides reuse Messages can be either payloads in or infrastructure beneath services Service-oriented architecture provides the framework for automation of common services Still, SOA has to be done well. It is cheaper and easier than ever to create badly designed applications and spaghetti integration
