SOA Suite forum on Oracle Technology Network (OTN) contains several posts on the use and configuration of the Database Adapter. This adapter can be used to perform database-related operations such as inserts, polling, invocation of PL/SQL, and so on in your SOA-environment. Some of these forum questions relate to inserting XML data into master/detail tables and how to use native database sequences to populate primary keys and automatically update associated foreign keys. I wrote an article
Invoice Processing in a Service-Oriented Environment that contains a step by step tutorial on how to achieve this.
