The WS-DAI family of specifications for web service data access and integration

The web service data access and integration (WS-DAI) family of specifications is developed by the Database Access and Integration Services working Group, which defines web service interfaces to data resources. The specifications include properties that can be used to describe a data service or the resource to which access is being provided, and define message patterns that support access to data resources. The development of standards for accessing databases from programming languages has saved countless hours of developer effort though improved portability and interoperability. The WS-DAI family of specifications should bring benefits to service-based computing, by making data resources available through consistent WSDL interfaces.
