Automated design methods Web service

web services in service-oriented architecture.

automated tools can aid in creation of web service. services using wsdl, possible either automatically generate wsdl existing classes (a bottom-up model) or generate class skeleton given existing wsdl (a top-down model).

a developer using bottom-up model writes implementing classes first (in programming language), , uses wsdl generating tool expose methods these classes web service. simpler develop may harder maintain if original classes subject frequent change.
a developer using top-down model writes wsdl document first , uses code generating tool produce class skeleton, completed necessary. model considered more difficult can produce cleaner designs , more resistant change. long message formats between sender , receiver not change, changes in sender , receiver not affect web service. technique referred contract first since wsdl (or contract between sender , receiver) starting point.
a developer using subset wsdl (swsdl) (i.e. wsdl subset operation in original wsdl) can perform web service testing , top down development.
