Topics include writing internal timers, building reusable objects and using reusable object libraries, incorporating PL/SQL libraries and accessing built-in program units. On course completion, students will be able to:

• Customize complex Internet applications
• Build reusable modules for rapid productivity
• Develop and debug complex triggers and program units
• Control presentation with windows, canvases and dialog boxes
• Building specialty stored procedure data blocks
