Abstract: A data providing web service returns a collection of objects without any side effects. The Web Service MEDiator (WSMED) system provides general SQL query capabilities. To make any data providing system into a data providing web service WSMED includes a web service generator that automatically deploys the operations required to access a data source. The web service generator is used also for defining the web service interface to WSMED itself to provide SQL query functionality to query and join any data providing web services. Search of any data providing web service from a browser can be done without any need for installing software.
Keywords: web service operations; web service queries; adaptive parallelisation; query optimisation; web service generator; web services; SQL query functionality; data search; web search.
