This class introduces participants to PL/SQL and helps them understand the benefits of this powerful programming language. In the class, participants learn to create PL/SQL blocks of application code that can be shared by multiple forms, reports, and data management applications. Participants learn to create procedures, functions, packages, and database triggers. Participants use iSQL*Plus to develop these program units. Participants also learn to manage PL/SQL program units and database triggers, to manage dependencies, to manipulate large objects, and to use some of the Oracle-supplied package.

This course helps Participants prepare to successfully pass the Oracle certification exam #1z0-147 to become an Oracle PL/SQL Developer Certified Associate (OCA-PL/SQL Developer).
