Oracle Application Express (APEX) 4.0 includes enhancements to interactive reporting, flash charts, and report printing capabilities. Interactive reports now feature a search bar, actions menu for formatting and exporting, and the ability to save customized report views. Flash charts have been updated to use the new AnyChart 5 engine, providing additional chart types like gauges and gantt charts. Report printing leverages Oracle BI Publisher or Apache FOP for high-fidelity output to PDF, Word, and other formats from APEX applications and reports. A demonstration shows these updated features in action.
