What you will learn
In this course, you will build, test and deploy Internet
applications with Oracle Forms. Working in a graphical user
interface (GUI) environment, you learn how to build forms with user
input items such as check boxes, list items, and radio groups. You
will also display Form elements in multiple windows and customize
data access by creating event-related triggers. This is one of
the three exams required to achieve the OCP Developer Certification.
