In this class you will learn how to get started building applications in Oracle APEX. We will focus on how to report and manage data declaratively by using Report and Form components. No previous knowledge or strong technical skills are required for this class, so it is well suited for users that are not software developers. We will also explore some of the overall architecture so users have a better frame of reference for how their applications are working. This class is delivered over Three Sessions, each session is four hours. |
