Direct to Web Services allows you to create a Web service that lets its clients access data in your data store by invoking Web service operations. Although this approach is similar to Direct to Web and Direct to Java Client in its use of a data model and rule sets, the target users for Web service applications are other applications, not people.
You use the Web Services Assistant to determine which data entities are accessible by your Web service clients and the type of operations they can execute on them, such as search, insert, delete, and update. You accomplish this without writing a single line of code.
