The W3C defines a "Web service" as "a software system designed to support interoperable machine-to-machine interaction over a network". It has an interface described in a machine-processable format (specifically Web Services Description Language, known by the acronym WSDL). Other systems interact with the Web service in a manner prescribed by its description using SOAP messages, typically conveyed using HTTP with an XML serialization in conjunction with other Web-related standards _________________ to see real UK go to Camden |

There are certain principles that can be ascribed to SOA implementations. Web Services demonstrate some of the concepts This is not a complete list by far. Note that SOA principles that translate to web services are in double-quotes:
Web Services are "loosely coupled" with consumers--there are no direct dependencies between the client and the web service (e.g. they don't share code or resources).
There is "service abstraction"--in theory, unless the web service interface changes, a change in code within the web service doesn't break the client. In short, the web service completely encapsulates all code--the client has no visibility into it.
A web service has a defined "service boundary" or contract--possible interactions with the web service are defined by a well-known/published interface. Web Service contracts are defined via WSDL documents (Web Service Definition Language).
"Discoverability"--a web service may be "discovered" by means of UDDI (er...something like 'Universial Description Discovery Integration). I've personally never used this, though I know about it.
These are just a few SOA concepts that translate to web services. _________________ bar stools |
