In this course, students learn the fundamentals of SQL and PL/SQL and understand the benefits of the programming languages. Students learn the concepts of relational databases.

Delivery format(s)
In this course, students learn the fundamentals of SQL and PL/SQL and understand the benefits of the programming languages. Students learn the concepts of relational databases.This course provides the essential SQL skills that allow developers to write queries against single and multiple tables, manipulate data in tables, and create database objects. Students also learn to use single row functions to customize output, use conversion functions and conditional expressions and use group functions to report aggregated data. Additionally, students learn to create PL/SQL blocks of application code that can be shared by multiple forms, reports, and data management applications.
