The document discusses Carnival Cruise Lines' migration of its shipboard applications from an outdated Oracle Forms character mode system to Oracle Application Express (APEX). The goals were to address issues with the old system like lack of support, compliance problems, and limited features. APEX was selected as the new platform because it provided a modern web interface without additional licensing costs and allowed reuse of existing PL/SQL code. The presentation demonstrates the new embarkation system built with APEX, showing improvements in performance, reduced data entry errors, and analytics dashboards. Future plans include further streamlining check-in processes.
