An open, extensible, federated, composable architecture that promotes service-orientation and is composed of autonomous, QoS-capable, vendor diverse, interoperable, discoverable and potentially reusable services implemented as web services. It is my personal opinion that any time a Service Component needs to interface to a legacy system, that an Adapter Pattern should be used. In order to perform the conversions, it may be necessary aoa an adapter to interface with many Service Components in order to perform data enrichment or break data apart into its fundamental data types.
