Web services and DB2 Universal Database
Web services enable the development and deployment of loosely coupled applications within a company or across industries.
You can create a Web service by wrapping an application so that it can be accessed using XML messages, which, in turn, are wrapped to mask the underlying transport protocol. The service is publicized in a standard-format registry, allowing people and applications to find and use the service over the Web. DB2 can be accessed as a Web service provider, and is usually paired with IBM WebSphere family products to provide a complete Web services framework.
One easy way to develop data-intensive Web services applications is through the DB2 document access definition extension (DADx) programming model. DADx files are simply XML documents that contain stored procedure references, XML Extender references, or traditional SQL. Best of all, DADx files can be created quickly without any Java programming.
