course focuses on the essential tasks of generating a fully functional Web-based application. You can run the generated applications using any Oracle Web server, however because we have built the course using WebDB, any references to a Web server are based on this product. You learned the basic uses of Oracle Designer in First Class. In this course you focus on designing and generating Oracle Web PL/SQL modules.
