    Introduction to Oracle SQL
    Oracle Forms Developer: Build Internet Applications

What you will learn:
This course introduces students to PL/SQL and helps them understand the benefits of this powerful programming language. In the class, students learn to create PL/SQL blocks of application code that can be shared by multiple forms, reports, and data management applications. Students learn to create procedures, functions, packages, and database triggers.

Students use iSQL*Plus to develop these program units. Students 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 packages.
