Purpose

Consuming Web Services in your Database applications extends the database’s reach and in turn, your application's as well. The inclusion of external data as part of database operations is not new, what's new is when the external data is only available as dynamic data, typically available as a Web service (eg. stock price, currency rate, weather forecast etc). This is where Web Service callouts from the Database come in the picture.

This Note addresses the Frequently Asked Questions on making Web Services callouts from the Oracle Database 10g & 11g and some other related questions.
