The Embedded PL/SQL Gateway (EPG) has been a feature of Oracle Database since version 10g. EPG enables a client to invoke a PL/SQL stored procedure through an embedded HTTP server. The content is generated dynamically using the PL/SQL Web Toolkit, a set of built-in packages provided in the database that handles the HTTP protocol.
This article provides an introduction to Oracle EPG for Flex users, outlines a simple PL/SQL framework, and shows how to create a Flex application that uses the framework.
