When building business intelligence applications data is important, but the key piece is making the data easily accessible so that the end-user can use it to improve upon the business. Oracle’s introduction of the 2nd Generation of BI Beans (10g R2) significantly improved the ability of inexperienced Java developers to create Complex Rich Business Intelligence Applications with minimal effort. This session explains how developers can take advantage the new features in JDeveloper and BI Beans 10g to create extremely powerful interactive business intelligence applications, which can be used for guided analyses by management. Attendees will see how to use Oracle 9i/10g, Oracle OLAP, JDeveloper 10g and BI Beans to build a powerful forecasting and what-if analysis application. An actual application will be presented. The experiences of the development process will be presented along with tips and techniques.
